As an ice cube warms and then melts, what is happening to its molecular kinetic energy?

• increasing

• decreasing

• staying the same

How is the cat being heated?

• condensation

• conduction

• convection

• radiation

Why does the temperature stay the same during a phase change diagram?

• Energy is being conserved to keep temp the same.

• Energy is being produced to increase temperature

• Energy is being used to break bonds between  molecules

• Energy is being released to create bonds

A flow movement where warmer air gets cools off and cooler air warms up. 

• Current

• Convection current

• Conduction current

• All of them

The faster molecules move, 

• the higher the temperature

• the less temperature

• the same temperature
