When a block of metal is heated but does not change state, the average kinetic energy of its particles increases. This is measured as an increase in the block
Answer Details
Temperature is the measure of the average kinetic energy of the particles in a substance. When a metal block is heated without changing state, the particles vibrate faster, meaning their average kinetic energy increases. This increase in kinetic energy is detected and measured as a rise in temperature.
Heating a metal block does not change its mass (mass is conserved and does not depend on temperature) or its weight (which depends on mass and gravitational field strength, neither of which changes with heating). A solid metal block does not produce gas when heated below its boiling point, so "volume of gas produced" is not relevant here.
