10 Questions
What happens to the kinetic energy of particles as the temperature rises?
It increases
Why is compressed natural gas (CNG) used as fuel in vehicles?
Because large volumes of CNG can be compressed into a small cylinder for easy transport
How do we perceive the smell of hot cooked food from a kitchen located far away?
The smell particles mix with air particles and diffuse rapidly to reach us
Why do gases show the property of diffusing very fast into other gases?
Due to the large space between gas particles
What is the minimum temperature at which a solid melts to become a liquid at the atmospheric pressure called?
Melting point
Why does the temperature of a solid remain the same during the process of melting?
The heat energy gets hidden into the contents of the beaker and is known as latent heat
What is the term used to describe the process of a liquid changing into a gas at a certain temperature?
Vaporization
What is the minimum temperature at which a liquid starts boiling at atmospheric pressure called?
Boiling point
Particles in water at 00 C (273 K) have more energy compared to particles in ice at the same temperature. What provides these particles with more energy?
The increased kinetic energy due to higher temperature
What term is used to describe the amount of heat energy required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point?
Latent heat of fusion
