• 100 C

Do you remember, during the lab, we put ice beaker over fire. Ice melt to water, then water turned into bubble gas. Solid -> Liquid -> Gas. The temperature went up. But when ice is "melting", the temperature stayed the same . When the water was "boiling", the temperature also stayed the same.

When the ice melting and the water was boiling, the temperature__________?

• Increase

• Decrease

• same
