Science 10 Quarter 4 Summative Test No. 1

In order to solve gas law calculations, temperature must be measured in:

• Celsius

• Kelvin

• It doesn't matter

• Fahrenheit

The relationship of which two variables are compared in Boyle's Law?

• volume & moles (amount of gas)

• pressure & volume

• temperature & pressure

• volume & temperature

How is volume measured?

• L

• Kpa

• mmHg

• 0C

State the relationship between temperature and volume in Charles' law.

• Randomly related

• No relationship

• Directly proportional

• Indirectly proportional

According to Boyle's law, at constant temperature, as the pressure of a given sample of gas is increased, the volume will ____________.

• Increase

• Decrease

• Remains the same

• I don't know

What is the formula Charles' Law?

• VT = VT

• 1 / V1 = T2 / V2

• V = T

• V1 / T1 = V2 / T2

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂

• P₁V₁/P₂V₂

• P₁V₂=P₂V₁

• P₁/V₁=P₂/V₂

Records show that the incident of tire explosion is high during summer season. Which of the following gives the best explanation for this observation?

• There are more travelers during summer vacation.

• High temperature during summer season causes the air inside the tire to expand.

• There is too much air inside the tires.

• Vehicles’ tires are not well maintained.

Give an example of a practical application of Boyle's law.

• A practical application of Boyle's law is in scuba diving, where the pressure of the gas in the scuba tank decreases as the diver ascends to the surface, causing the volume of the gas to increase.

• Boyle's law is applied in agriculture to regulate the pressure in greenhouses for optimal plant growth.

• Boyle's law is used in construction to calculate the pressure changes in building materials at different elevations.

• Boyle's law is used in cooking to determine the pressure needed to cook food at high altitudes.

Give an example of a practical application of Charles' law.

• A practical application of Charles' law is in refrigerators, where the volume of the gas inside the refrigerator decreases as the temperature of the gas decreases.

• A practical application of Charles' law is in car engines, where the volume of the gas inside the engine remains constant regardless of the temperature.

• A practical application of Charles' law is in scuba diving tanks, where the volume of the gas inside the tank decreases as the pressure increases.

• A practical application of Charles' law is in hot air balloons, where the volume of the gas inside the balloon increases as the temperature of the gas increases.
