"Heat" itself does not rise; heat transfers [moves] by conduction, radiation, and convection [convection is the one that best relates to what your question asks].
Your question refers to a warmer fluid [gasses as such as air for one example, or the same thing occurs in liquids, as water for one example] rising in cooler surrounding fluid.
The reason a warmer fluid [gas or liquid] rises in surrounding fluid is as answer one and two state, as both are correct in that both are causes, except that one is the cause for the other.
The combined answer is: As the average kinetic energy of the atoms of a fluid increases, the density of the fluid becomes less [it get "lighter"] and therefore rises ["floats"] in the surrounding fluid until it reaches a level where its temperature and density are the same as the surrounding fluid [equilibrium]. At that point the mass of fluid will cease to rise.
We refer to this process as "convection."j3h.
Answer Ok so we're all right.Except that "right" is subjective and only correctly classified when we inject perspective. Heat will always rise with respect to the ground we walk on, no matter the temperature, state of matter, or any other physical property.
The true reason that heat rises is due to something not yet mentioned... GRAVITY! To be more precise, in a positively excited atom/molecule, the electrons create a larger orbital shell whereby making the atom/molecule as a whole more "empty" or "porous", void of matter. Believe it or not, this minutely small difference is enough to slightly loosen gravity's electromagnetic grip on the atom/molecule allowing it to slip further away from gravity's source... the planet's core. This is why even a lone positively excited atom/molecule in a vacuum will rise toward the top of the container, just as it would if there were trillions.
Answer - RebuttalGravity as discussed above, is not the cause, but instead the DIFFERENCE IN BOUYANCY created by the "... more 'empty' or 'porus...' thus LESS DENSE weight of the fluid/gas molecule. The change in density does not change the mass of the molecule.
Heat rises because when air is heated, it becomes less dense and expands, causing it to become lighter than the surrounding cooler air. This lighter, warmer air then rises above the cooler air, creating convection currents and leading to the overall upward movement of heat.

Will temperature rise if it's hot?
No, the temperature will not rise if it's already hot. Temperature is a measure of the intensity of heat present in a substance, so if it's already hot, the temperature will remain constant until there is a change in the heat input or output.
Will ice rise in temperature straight away when heated?
No, ice will not immediately rise in temperature when heated. Initially, the heat energy will cause the ice to melt and transition into water. Only after the ice has completely melted will the temperature of the water start to rise.
What is the temperature rise of 250 cfm of air if an electric heater adds 8500 btus to the air?
Assuming no heat loss, the temperature rise would be approximately 36 degrees Fahrenheit. This calculation is based on the specific heat capacity of air, which is about 0.24 BTU/lb°F. The formula for calculating temperature rise is: Temp Rise = Q / (m * Cp), where Q is the energy added in BTUs, m is the mass flow rate of air in lbs per minute, and Cp is the specific heat capacity of air in BTU/lb°F.
For convection currents in the asthenosphere where does the heat come from?
The heat in the asthenosphere primarily comes from the heat generated by the decay of radioactive isotopes in the mantle and the residual heat from Earth's formation. This heat causes the material in the asthenosphere to become less dense and rise, generating convection currents.
Why will a rise in temperature result in a rise of sea levels?
A rise in temperature causes ice caps and glaciers to melt, contributing to an increase in the volume of water in the oceans. Warmer temperatures also cause water to expand, further adding to rising sea levels.
Why does your temperature gauge rise and lower only when you have the heat on?

What things can effect air to rise?
Heat can cause air to rise :)
Does radiated heat rise?
yes
What happens to an object's temperature when you heat?
The temperature of the object will rise because of the heat.
Heat energy makes water and what rise into the air?
Heat energy makes water evaporate and rise into the air as water vapor.
What does heat makes air do?
Heat makes air less dense and therefore rise.

How are the amount of of heat transferred and the change in temperature related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.
How are the amount of heat transferred and change in temperature of water related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.

Do endothermic organisms temperatures rise and the temperatures rise?
endothermic means it is absorbing heat. the heat within the organism would be warmer than the surrounding environment over time.
