When you apply increasing thermal energy to a certain material, it reaches a temperature of 50 degrees C. However, when it reaches this temperature, applying more increasing thermal energy does not cause the temperature to rise. Which of the following best explains what is happening?

Question

a. The system is having its heat leaking out that is not going into the material

b.The material is at its phase change temperature and the thermal energy is going to change the phase instead of increase the temperature

c. The material is made of a heat resistant alloy that is preventing the thermal energy from being fully absorbed

d.The material has already absorbed enough thermal energy and cannot absorb any more

Is it d.?

Answer 1

b is probably better...
