increase
As molecules move faster, they cause friction, which increases the temperature of the molecules.
Molecules react to thermal energy, or heat, as well as pressure. When you increase the temperature of molecules, they will increase their vibration and movement. Pressure can also allow molecules to move from one area to another.
The energy from the boiling water is transferred to the mug through conduction. The hot water molecules collide with the mug's molecules, causing them to vibrate and increase in temperature.
As temperature increases, water molecules gain energy and move faster, causing them to spread out and increase in volume, resulting in a decrease in density. Conversely, as temperature decreases, water molecules slow down and come closer together, leading to a decrease in volume and an increase in density.
According to Boyle's Law of Pressure-Volume Relationship, an increase in the pressure of a gas will decrease it's volume. And according to Charles's Law of Temperature-Pressure Relationship, an increase in pressure causes an increase in temperature.
As you go higher in the atmosphere, the temperature generally decreases. This is because the atmosphere becomes less dense and there are fewer molecules to retain heat.
increase
No. The energy you might be referring to is kinetic energy which is the energy possessed by individual water molecules. An increase in kinetic energy will be percieved as and increase in temperature. Similarly a decrease in kinetic energy will be percieved as a decrease in temperature.
The temperature in flask A rose because heat was transferred from the surroundings to the contents of the flask, increasing the kinetic energy of the molecules and causing their temperature to increase.
When a volume of air is compressed, its temperature increases due to an increase in kinetic energy of the air molecules. This is because the compression process causes the air molecules to be crowded closer together, leading to collisions that result in an increase in temperature.
decrease
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
