A steady force pushes in the piston
of a well-insulated cylinder. In this
process, the temperature of the gas

• Increases
• Stays the same
• Decreases
• Not enough info

Dragging an object across a rough surface makes it warm, or even hot. The temperature increase occurs because of

• Work
• Heat
• Thermal
• Both work and heat

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed
