Questions and Answers
At a given temperature, do all particles in a beaker have the same amount of energy?
At a given temperature, do all particles in a beaker have the same amount of energy?
- No, only gas particles have varying energy.
- Yes, because they are in thermal equilibrium.
- Yes, because temperature is constant.
- No, not all particles have the same kinetic energy. (correct)
Why must vapor pressure be measured in a closed container?
Why must vapor pressure be measured in a closed container?
- To ensure accurate measurement of pressure.
- To prevent particles from escaping.
- To avoid interference from external factors.
- To maintain equilibrium between vapor and liquid. (correct)
- To increase the evaporation rate.
How does evaporation affect the temperature of a liquid?
How does evaporation affect the temperature of a liquid?
- It has no effect on temperature.
- It increases the temperature by releasing heat.
- It lowers the temperature by decreasing kinetic energy. (correct)
- It causes the liquid to freeze.
- It raises the temperature by increasing kinetic energy.
