1. A method comprising: controlling the temperature of a liquid and providing that liquid to one side of a membrane;pre-humidifying gas, by other than the membrane, prior to being provided to the other side of the membrane;providing the pre-humidified gas to be humidified to the other side of the membrane, the pre-humidified gas provided to the other side of the membrane having a relative humidity greater than or equal to about 40%; andhumidifying the pre-humidified gas using the liquid via the membrane,wherein the temperature of gas on the other side of the membrane is controlled by the temperature of liquid on the one side of the membrane, and wherein the controlling the temperature of the liquid comprises controlling the temperature of the liquid on the basis of gas temperature entering or leaving the other side of the membrane during the humidifying. 2. The method of claim 1, comprising conditioning the temperature of the liquid upstream of the membrane. 3. The method of claim 1, further comprising conditioning the temperature of the gas upstream and/or downstream of the membrane. 4. The method of claim 1, further comprising changing the temperature to which the liquid or gas is controlled. 5. The method of claim 1, further comprising projecting a patterned beam of radiation onto a radiation-sensitive substrate using a lithographic apparatus and blowing the humidified gas within the lithographic apparatus. 6. The method of claim 1, wherein the pre-humidified gas has a relative humidity greater than or equal to about 40% and less than 90%. 7. The method of claim 1, wherein the membrane has a surface which is liquidphilic to the liquid. 8. An apparatus comprising: a membrane;a liquid temperature conditioner to condition the temperature of a liquid;a first conduit to guide the liquid from the liquid temperature conditioner to one side of the membrane;a pre-humidifier, other than the membrane, to pre-humidify gas upstream of the membrane;a second conduit to guide the pre-humidified gas, to be humidified via the membrane, to contact the membrane at the other side of the membrane, wherein the pre-humidified gas that contacts the membrane has a relative humidity greater than or equal to about 40%; anda controller to control the temperature of the gas by controlling the liquid temperature conditioner to control the temperature of the liquid, wherein the controller is configured to control the temperature of the liquid on the basis of gas temperature entering or leaving the other side of the membrane during the humidification of the gas. 9. The apparatus of claim 8, further comprising a gas temperature conditioner to condition the temperature of the gas upstream and/or downstream of the membrane. 10. The apparatus of claim 8, wherein the controller is configured to control the liquid temperature conditioner to change the temperature to which the liquid or gas is conditioned. 11. The apparatus of claim 8, wherein the liquid temperature conditioner is configured to receive control signals indicative of a desired temperature of the liquid based on a desired temperature of the gas. 12. The apparatus of claim 8, wherein the temperature of the gas is the temperature of gas leaving the other side of the membrane. 13. The apparatus of claim 8, further comprising a lithographic apparatus configured to project a patterned beam of radiation onto a radiation-sensitive substrate, the lithographic apparatus comprising a purging system to blow humidified gas from the other side of the membrane within the lithographic apparatus. 14. The apparatus of claim 13, wherein the lithographic apparatus is an immersion lithographic apparatus configured to project the patterned beam of radiation through immersion liquid onto the radiation-sensitive substrate and the purging system is selected from: a liquid confinement system to confine the immersion liquid, a drying station to dry the immersion liquid from an object, or an evaporation reducing system to reduce evaporation of the immersion liquid from an object. 15. The apparatus of claim 8, wherein the pre-humidifier is configured to provide pre-humidified gas having a relative humidity greater than or equal to about 40% and less than 90%. 16. The apparatus of claim 8, comprising a first outlet for the pre-humidified gas with a relative humidity greater than or equal to about 40% and less than 90% and a second outlet for the gas humidified by the membrane with a relative humidity greater than or equal to 90%. 17. The apparatus of claim 8, wherein the membrane behaves in a non-porous manner with regard to the liquid such that the liquid does not enter the membrane, and in a porous manner with regard to the vapor of the liquid. 18. An apparatus comprising: a liquid temperature conditioner to condition the temperature of a liquid;a membrane having a surface which is liquidphilic to the liquid;a first conduit to guide the liquid from the liquid temperature conditioner to one side of the membrane;a pre-humidifier, other than the membrane, to pre-humidify gas upstream of the membrane;a second conduit to guide the pre-humidified gas, to be humidified via the membrane, to contact the membrane at the other side of the membrane, wherein the pre-humidified gas that contacts the membrane has a relative humidity greater than or equal to about 40%; anda controller to control the temperature of the gas by controlling the liquid temperature conditioner to control the temperature of the liquid, wherein the controller is configured to control the temperature of the liquid on the basis of gas temperature entering or leaving the one side of the membrane during the humidification of the gas. 19. The apparatus of claim 18, further comprising a lithographic apparatus configured to project a patterned beam of radiation onto a radiation-sensitive substrate, the lithographic apparatus comprising a purging system to blow humidified gas from the other side of the membrane within the lithographic apparatus. 20. The apparatus of claim 19, wherein the lithographic apparatus is an immersion lithographic apparatus configured to project the patterned beam of radiation through immersion liquid onto the radiation-sensitive substrate and the purging system is selected from: a liquid confinement system to confine the immersion liquid, a drying station to dry the immersion liquid from an object, or an evaporation reducing system to reduce evaporation of the immersion liquid from an object.
