Question

Heat can bring in:

• A. change in temperature
• B. change in state
• C. chemical change
• D. no change in volume

Answer 1

Answer: (A), (B), (C)

The correct options are
A change in temperature
B change in state
C chemical change

When an object is heated, the kinetic energy of the molecules increases and thus the temperature also increases.
Heating can also result in change of state. That is, on heating solids, it will change into liquids and on heating liquids, it will change into gas.
Heat can bring in chemical change. For example on heating potassium permanganate it decomposes to potassium manganate, magnesium oxide and oxygen gas.
