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

Answers

Answer 1

Answer:

The temperature change indicates an increase in the average kinetic energy of the molecules in a sample is 15°C to 298 K. Thus option 1 is correct.

What is kinetic energy?

Kinetic energy is defined as a form of energy that an object or particle has by the reason of its movement.

It can also be defined as the measure of the work that an object does by virtue of its motion.

Average kinetic energy is defined as a product of half of the mass of each molecule and the square of RMS speed.

The kinetic energy id directly proportional to temperature, with increase in temperature kinetic energy increases.

Thus, the temperature change indicates an increase in the average kinetic energy of the molecules in a sample is 15°C to 298 K. Thus option 1 is correct.

Answer 2

Answer: 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).
