Question 11

Internal energy

Answer 11

The energy stored inside a system by the particles (atoms and molecules) that make up a system. Internal energy is the total kinetic and potential energy of all the particles.

Question 12

The energy stored inside a system by the particles (atoms and molecules) that make up a system. Internal energy is the total kinetic and potential energy of all the particles.

Answer 12

Internal energy

Question 13

Kinetic energu

Answer 13

Energy stored within moving objects

Question 14

Energy stored within moving objects

Answer 14

Kinetic energu

Question 15

Potential energy

Answer 15

Energy stored in particles because of their position. The further apart the particles are, the greater the potential energy

Question 16

Energy stored in particles because of their position. The further apart the particles are, the greater the potential energy

Answer 16

Potential energy

Question 17

Question 27

Eureka can

Answer 27

Used to measure the volume if an irregular object by displacement of water

Question 28

Used to measure the volume if an irregular object by displacement of water

Answer 28

Eureka can

Question 29

Gas pressure

Answer 29

The force exerted by gases on a surface as the particles collide with it. The pressure produces a net force at right angles to the wall of the gas container or surface

Question 30

The force exerted by gases on a surface as the particles collide with it. The pressure produces a net force at right angles to the wall of the gas container or surface

Answer 30

Gas pressure

Question 31

Gas pressure and temperature

Answer 31

As temperature increases, gas pressure increases if the volume stays constant. The particles move more quickly, therefore collide more frequently with the walls of the container.

Question 32

As temperature increases, gas pressure increases if the volume stays constant. The particles move more quickly, therefore collide more frequently with the walls of the container.

Answer 32

Gas pressure and temperature

Question 33

Boyle’s Law

Answer 33

The pressure of a gas is inversely proportional to its volume. When the volume increases, the pressure decreases, assuming the temperature remains constant. Pressure x Volume = Constant P1V1 = P2V2 (P1 is intial gas pressure and P2 is final gas pressure, same with V1 and V2 but with volume)

Question 34

The pressure of a gas is inversely proportional to its volume. When the volume increases, the pressure decreases, assuming the temperature remains constant. Pressure x Volume = Constant P1V1 = P2V2 (P1 is intial gas pressure and P2 is final gas pressure, same with V1 and V2 but with volume)

Answer 34

Boyle’s Law

Question 35

Work

Answer 35

The transfer of energy by a force

Question 36

The transfer of energy by a force

Answer 36

Work

Question 37

Work on gases

Answer 37

Doing work on a gas increases the internal energy of the gas and can cause an increase in the temperature of the gas

Question 38

Doing work on a gas increases the internal energy of the gas and can cause an increase in the temperature of the gas

Answer 38

Work on gases
