Properties of Matter: Intensive & Extensive
1 / 10
Which pair consists of only intensive properties?
Explanation: Density and temperature are intensive, as they do not depend on the amount of matter. The other pairs include extensive properties like mass, volume, weight, energy, length, and surface area
2 / 10
If the mass of a sample doubles, what happens to its density?
Explanation: Density (mass/volume) is intensive. If both mass and volume double proportionally, density stays constant for the same substance.
3 / 10
Which property is useful for comparing two different samples of the same substance?
Explanation: Melting point is intensive, so it remains the same for any sample of a substance (e.g., ice melts at 0°C), making it ideal for comparison.
4 / 10
The volume of a gas in a container is:
Explanation: Volume is extensive because it increases with the amount of gas. More gas in the container means a larger volume.
5 / 10
Which of the following is NOT an extensive property?
Explanation: Pressure is an intensive property, as it does not depend on the amount of matter. Energy, weight, and surface area scale with the sample size.
6 / 10
 If you divide a sample of water into two equal parts, which property remains unchanged?
Explanation: Specific heat is an intensive property, staying constant regardless of the sample size. Mass and volume halve when the sample is divided.
7 / 10
Which property would help identify a material regardless of its size?
Explanation: Density is an intensive property, unique to a material (e.g., gold has a specific density), and does not vary with sample size.
8 / 10
The temperature of a substance is an example of:
Explanation: Temperature is intensive because it does not change with the amount of substance. A small or large sample of water at 25°C has the same temperature.
9 / 10
Which of the following is an extensive property?
Explanation: Extensive properties, like mass or volume, depend on the amount of matter in the sample. More matter means a larger value.
10 / 10
What is an intensive property of matter?
Explanation: Intensive properties, like density or temperature, remain the same regardless of the sample size or amount of matter.
