General Science - Physics (Basics)
When heat is supplied to a substance, its temperature rises because:
AThe average kinetic energy of particles increases
BThe potential energy of particles increases
CThe total mass of the substance increases
DThe number of particles increases
Step-by-Step Solution
  1. Step 1: Understand the effect of heat on temperature

    Heat supplied increases the energy of particles, affecting their motion.
  2. Step 2: Analyze particle energy changes

    Temperature rise corresponds to an increase in average kinetic energy of particles, not potential energy or mass changes.
  3. Final Answer:

    The average kinetic energy of particles increases → Option A
  4. Quick Check:

    Temperature rise = increased average kinetic energy ✅
Quick Trick: Temperature depends on particle motion, not mass or number.
Common Mistakes:
MISTAKES
  • Confusing kinetic energy with potential energy or mass increase.
