Socrative Quiz - Temperature
• Question 1
• Define temperature in your own words.
• Temperature is the measurement of the average
movement (kinetic energy) of the particles in a
substance or object.
• Question 2
• Describe thermal expansion in terms of the
movement of particles.
• When particles get hot, they move faster, gaining
kinetic energy, and start to spread out. Therefore the
particles take up more space.
• Question 3
• Describe thermal expansion in terms of the
movement of particles.
• When particles get hot, they move faster, gain kinetic
energy, and spread out more. Therefore the particles
take up more space.
• Question 4
• Which is the coldest temperature?
• 0 K is the coldest temperature. It is the same as -273
degrees C (not F).
• Question 5
• Does temperature depend on the amount of
the substance? Explain.
• Temperature of a substance only depends on how fast or
slow the particles are moving. It does not depend on how
many particles there are in the substance.
• Question 6
• Why do you think heating a full pot of soup on
the stove could cause the soup to overflow?
• When particles get hot, they move faster and spread out
(expand) so they take up more space. So if the pot is totally
full of soup, it will overflow when the particles spread out.
• Question 7
• What happens to the density of a
substance during thermal expansion?
• The amount (mass) of the substance stays the same
but since hot particles move faster than cold particles,
they will spread out and take up more space. So hot
substances are less dense than cold substances.
• Question 8
• A glass of cold water whose particles had a low
average kinetic energy was placed on a table.
The average kinetic energy of the water in the
glass increased, while the average kinetic
energy of the part of the table under the glass
decreased. Explain what you think happened.
• The warmer table (more kinetic energy) transferred
some of its heat energy through conduction to the
colder particles (less kinetic energy) in the glass,
thereby making the table colder and the water in the
glass warmer. This is because heat moves from
warmer areas to colder areas.
