Question 1

At constant volume, the absolute pressure of a gas is inversely proportional to the absolute temperature.

Accepted Answer

According to Gay-Lussac's Law, at constant volume, the pressure of a gas is directly proportional to its absolute temperature.

Question 2

When a bimetallic strip is cooled, the strip will bend toward the side

Accepted Answer

When a bimetallic strip is cooled, the side with the larger coefficient of linear expansion will contract more than the side with the smaller coefficient of linear expansion. This will cause the strip to bend toward the side with the larger coefficient of linear expansion.

Question 3

Two systems are in thermal equilibrium. The two systems are at the same

Accepted Answer

Two systems in thermal equilibrium are at the same temperature, as per the zeroth law of thermodynamics.

Question 4

Equal volumes of gas at the same pressure and temperature contain equal numbers of molecules.

Accepted Answer

This statement is a restatement of Avogadro's Law, which states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules.

Question 11

When a bimetallic strip is heated, the strip will bend toward the side

Accepted Answer

When a bimetallic strip is heated, it bends toward the side with the smaller coefficient of linear expansion because the side with the larger coefficient expands more, causing the strip to bend towards the less expanding side.

Question 12

A machinist needs to remove a tight fitting pin of material A from a hole in a block made of material B. The machinist heats both the pin and and the block to the same high temperature and removes the pin easily. What statement relates the coefficient of thermal expansion of material A to that of material B?

Accepted Answer

The answer of A machinist needs to remove a tight...

Accepted Answer

The answer of State the Zeroth Law of Thermodynamics....

Question 14

The volume of a given amount of gas is inversely proportional to the absolute temperature when the pressure is kept constant.

Accepted Answer

The volume of a given amount of gas is directly proportional to the absolute temperature when the pressure is kept constant, according to Charles's Law.

Question 15

If a thermometer measures the temperature of two objects as being equal, you can conclude that the objects will be in thermal equilibrium if they are brought into thermal contact.

Accepted Answer

When two objects have the same temperature as measured by a thermometer, it means that they are in thermal equilibrium with respect to each other. Therefore, if they are brought into thermal contact, there will be no transfer of heat between them as they are already at the same temperature.

Question 16

The triple point of water occurs only at a unique temperature and pressure.

Accepted Answer

The triple point of water is a specific condition where water can coexist in solid, liquid, and gas phases, occurring at precisely 0.01°C and 611.657 pascals.

Question 17

Describe the two step process used to calculate thermal stress in a beam with ends which are rigidly fixed.

Accepted Answer

The answer of Describe the two step process used to...

Question 18

If a thermometer measures the temperature of two objects as being equal, you can conclude that if the objects are placed in thermal contact, no heat will flow between them.

Accepted Answer

If two objects are at the same temperature, their thermal energy is in equilibrium and no net heat flow occurs between them when they are placed in thermal contact. This is known as the Zeroth Law of Thermodynamics.

Question 19

The volume of a gas is inversely proportional to the absolute pressure applied to it when the temperature is kept constant.

Accepted Answer

This statement describes Boyle's Law, which states that for a given mass of gas at constant temperature, the volume of the gas is inversely proportional to its pressure.

Question 20

Explain the operation of a constant-volume gas thermometer.

Accepted Answer

The answer of Explain the operation of a constant-volume gas...
