Heat moves from the water to the air, and the water gets colder
Heat moves from the air to the water, and the water gets hotter
Heat moves from the air to the water, and the water gets colder
A container of water and an equal-sized container of oil are heated at the same rate. After several minutes, the temperature of the oil has risen 20 degrees C, but the temperature of the water has only increases by 8 degrees C. What explains this?
Question 6 options:
The water contains more atoms, so it has more thermal energy
It takes more energy to increase the temperature of water than to increase the temperature of oil
Heat moves from the water to the oil.
More heat was added to the oil than to the water.
As the temperature of an object increases, the atoms
Question 7 options:
slow down (energy decreases) and move closer (volume contracts)
slow down (energy decreases) and spread out (volume expands)
speed up (energy increases) and spread out (volume expands)
speed up (energy increases) and move closer (volume contracts)
