Compared with the Pacific Ocean, a cup of hot chocolate has (less or more thermal energy and a higher temperature)
less thermal energy and a higher temperature.
A tile floor feels colder on your bare feet than a wooden floor because the tile floor (is a better insulator or conducts more energy from your feet)
conducts more energy from your feet.
If two substances have the same temperature, then ( the substances have the same average kinetic energy or the substances have equal thermal energies)
the substances have the same average kinetic energy.
Alcohol in a thermometer rises as a result of ( thermal contraction or thermal expansion)
Some bridges are constructed with small gaps called expansion joints because (concrete segments expand on hot days or it allows the bridge to raise and lower for passing boats)
concrete segments expand on hot days.
A bimetallic strip in a thermostate uncoils because of (thermal expansion or thermal contraction)
The temperature of a substance is determined by (how much of the substance you have or how fast the atoms or molecules of the substance are moving.)
how fast the atoms or molecules of the substance are moving.
Heat is (the same thing as temperature or the transfer of energy between objects that are at different temperatures.)
the same thing as temperature
At thermal quilibruim (no net change in either object's thermal energy occurs or None of the above)
NONE of the above
The total kinetic energy of the particles that make up a substance is (thermal energy or temperature)
Ice begins to melt at 0 degrees C. When an ice cube has just fully melted, its temperature (is the same as the melting point or is greater than the melting point)
is greater than the melting point.
When two objects reach thermal equilibrium (thermal energy is no longer transferred between the two objects, or both objects have the smae temperature, of on object may have more thermal energy)
one object may have more thermal energy.
The transfer of thermal energy from one substance to another through direct contact is (radiation, conduction or convection)
The transfer of thermal energy by the movement of a liquid or a gas is (convection, radiation, or conduction)
The handle of a metal spoon warms up when it is placed in a hot bowl of soup because of (convection or conduction)
Which of the following has the most thermal energy? (a pot of soup or a spoonful of soup)
a pot of soup
Hot objects atoms move fast or slow?
Cold objects atoms move fast or slow?
hot objects atoms move fast and cold objects atoms move slower.
is measured in a thermometer by the expansion and contraction of a liquid metal called Mercury.
What are the 3 temperture scales
Fahrenheit, the scale where water freezes at 32 degrees, Celsius shows water freezes at zero degrees, and Kelvin shows absolute zero.
