Does the composition of an object affect the final temperature of in objects. This is in terms of thermal equilibrium.

yes.

Can please explain to me why that is?

Also by composition it means what the objects are made out of right? So if they are Aluminum then they would be a conductor of heat?

The composition means mass, and thermal capacity. Both of those affect heat absorbtion.

Yes, the composition of an object can affect its final temperature when it is in thermal equilibrium with another object. Thermal equilibrium occurs when two objects are at the same temperature and there is no net flow of heat between them.

The temperature of an object is a measure of the average kinetic energy of its particles. Different materials have different internal structures and arrangements of particles, which can affect their ability to absorb and retain heat.

The specific heat capacity of a material is a measure of how much heat energy it can absorb or give off for a given change in temperature. Materials with higher specific heat capacities require more heat energy to raise their temperature compared to materials with lower specific heat capacities.

Additionally, different materials have different thermal conductivities, which determine the rate at which heat can be transferred through them. Materials with high thermal conductivities can transfer heat more efficiently than materials with low thermal conductivities.

Therefore, the composition of an object, including its specific heat capacity and thermal conductivity, can influence the rate at which it reaches thermal equilibrium with another object and the final temperature that is achieved.

In order to determine the final temperature of two objects in thermal equilibrium, you would need to consider their masses, specific heat capacities, and initial temperatures. You can use the formula:

Q = mcΔT

Where Q represents the heat energy transferred, m is the mass of the object, c is the specific heat capacity, and ΔT is the change in temperature. By equating the heat energy gained by one object to the heat energy lost by the other object, you can solve for the final temperature.
