Which statement is wrong?

1. Temperature measures the average kinetic energy of random motion, but not other kinds of energy.

2. When the same amount of heat produces different changes in temperature in two substances of the same mass, we say that they have different specific heat capacities.

3. Each substance has its own characteristic specific heat capacity.

4. Different substances have different thermal properties due to differences in the way energy is stored internally in the substances.

5. Adding the same amount of heat to two different objects will produce the same increase in temperature.

Answer #1

The Fifth statement is incorrect.

" 5. Adding the same amount of heat to two different objects will produce the same increase in temperature. " is INCORRECT.

This is because, " an increase in temperature for an body/Object depends on many factors such as the specific heat capacity, Thermal conductivity/Diffusivity of that material, the nature of that material etc... ".

The specific Heat capacities, coefficient of thermal conductivity/diffusivity, and the nature of material are the UNIQUE PROPERTY OF EACH AND EVERY MATERIAL. and hence, even if same amount of heat applied on different materials, the produced amount of heat will always be different.

Hence, The Fifth statement is incorrect !

Select all true statements. 195 oF is a higher temperature than 100 oC given the same pressure. The amount of greenhouse gases in the atmosphere have increased dramatically over the last half-century. The heat of vaporization is the amount of energy needed to convert a substance completely from a liquid to a gas at the boiling point. Two objects in thermal equilibrium are at the same temperature. In general, as external pressure increases, the temperature for boiling water decreases.

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...
