43 Which temperature change indicates an increase in the average kinetic energy of the molecules in a sample?(1) 15°C to 298 K (3) 305 K to 0°C
(2) 37°C to 273 K (4) 355 K to 25°C
The increase in the average kinetic energy of the molecules needs the increase of temperature. The relation of ℃ and K is n ℃ = m K -273. So if we change all the K unit to ℃ unit, we can get the answer is (1).
