Not necessarily. Heat is a form of Thermal Energy. In general Thermal energy is any form of motion of a particle. If you have a single electron you can already have four choices. Transversal Velocity on all 3 coordinate axes and vibration up and down. A molecule can also rotate around its center of mass. So an increase in thermal energy(i.e. heat absorbtion) does not necessarily mean a rise in Speed, it does not exclude the possibility though.

How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
because the heat is transferred to the molecules and gives them more kinetic energy
How does heat transfer to cups?
Heat transfer to cups (or other solid objects) happens on a molecular level; fast moving hot molecules (perhaps in your hot coffee) collide with slower moving cold molecules (in your cup) and speed them up, giving up some of their own momentum.
How does the speed of the molecules of a gas change when heated?
it moves faster
What happens to thermal energy if the molicules speed up?
Thermal energy increases when molecules speed up.
Does heat speed up slow down or destroy molecules that are being diffused?
Speed UP
What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
What is it called when heat energy required to break up the attraction of liquid molecules?
When liquid molecules absorb enough heat energy, evaporation occurs.
What food molecules do when penetraded by microwave?
Microwave energy excites the molecules of the food. This generates friction and heat at the molecular level. When food is heated, it causes the molecules to speed up, so artificially speeding up the molecules causes heat to be produced.
Will heat or direct sunlight affect the contents of a bottle or liqueur?
Yes! UV light from the sun can ionize the molecules in the liquor and heat will speed up oxidation.
What effect does the addition of heat usually have on the rate of a chemical reaction?
The addition of heat stimulates the molecules in the reaction. Because they will move faster, the reaction will speed up.
How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
How is electricity used to make the heater working?
Energy makes molecules rapidly move faster and faster, and when you make molecules move faster you are creating heat. So by using electricity(energy), you speed up the molecules of water, thus creating heat.
How would greenhouse gases retain energy in the atmosphere?
Greenhouse Gases (water, carbon dioxide, methane, SF6 etc.) are made up of at least two molecules. The bond size between the atoms in the molecules is such that it can absorb heat more easily than other molecules. When solar energy comes to the atmosphere they absorb the solar energy as heat then radiate it to other atmospheric (non-greenhouse) gases such as nitrogen and oxygen..
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
because the heat is transferred to the molecules and gives them more kinetic energy
How does heat transfer to cups?
Heat transfer to cups (or other solid objects) happens on a molecular level; fast moving hot molecules (perhaps in your hot coffee) collide with slower moving cold molecules (in your cup) and speed them up, giving up some of their own momentum.
What is the d layer made out of?
The ozone layer is made up of pure ozone molecules only. The molecules absorb the UV-C molecules.
