Is there any text stating that walls or objects made of force can or cannot conduct thermal energy?

For example: Wizard is pushed off edge of volcano into magma. Let's surmise he is able to cast Wall of Force or some other means that allow him to be inside a sphere of force.

Sphere hits lava, starts to sink. He's protected from the lava by the wall of force, but does the thermal energy from the lava "heat" up the wall of force which then heats the air inside and eventually trap him inside a death oven where he cooks inside his own Wall of Force?
