3Question 3.
What is the definition of latent heat of fusion?
- A. Heat required to increase temperature
- B. Heat required for phase change without temperature change
- C. Heat of reaction
Show hintHide hint

4Question 4.
True or False: The temperature of ice rises as it melts.
- True
- False
Show hintHide hint
Consider the heating process of solid to liquid.
Question 5.
Assess the energy absorption in a scenario where a glacier melts completely due to rising temperatures. Assuming a glacier mass of 1,000,000 kg and a latent heat of fusion of 334,000 J/kg, calculate the heat absorbed.
Show hintHide hint
Follow the same formula we learned for smaller masses.
Question 6.
