What is the atmospheric pressure inside the oven?

• 2.0 * 10^4 pascals

• 1.0 * 10^4 pascals

• 2.0 * 10^5 pascals

• 1.0 * 10^5 pascals

How does the air inside the oven behave?

• As a liquid

• As a solid

• As a real gas

• As an ideal gas

What is the relationship between internal energy and temperature for an ideal gas?

• Internal energy is independent of temperature.

• Internal energy increases with temperature.

• Internal energy decreases with temperature.

• Internal energy is zero at all temperatures.

What is the formula for the kinetic energy of a particle in an ideal gas?

• k * T

• 3/2 * k * T

• 1/2 * m * v^2

• m * g * h

What happens to the internal energy formula when temperature is canceled out?

• It becomes PV * 2/3.

• It becomes zero.

• It becomes PV * 1/2.

• It becomes PV * 3/2.

What happens to the velocity of particles when temperature increases?

• Velocity decreases.

• Velocity becomes zero.

• Velocity increases.

• Velocity remains constant.

Why does the pressure remain constant despite an increase in temperature?

• The container expands.

• The container contracts.

• Some particles escape the container.

• The particles slow down.

What is the relationship between force and pressure?

• Pressure is force times area.

• Pressure is force over area.

• Pressure is force plus area.

• Pressure is force minus area.

What is the significance of PV = nKT in this context?

• It explains how pressure remains constant.

• It describes the volume of the oven.

• It calculates the mass of the particles.

• It measures the temperature in Celsius.
