The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)

What does the amount of heat needed to raise an objects temperature depend on?

The amount of heat needed to raise an object's temperature depends on its mass, its specific heat capacity, and the temperature change desired. Objects with higher mass require more heat to raise their temperature, while those with higher specific heat capacities absorb more heat for the same temperature change.


Would you raise or rise the temperature?

Raise would be correct in this situation. Can you specify the exact sentence it is in in a new question?


Is mass of two object affect the final temperature?

The mass of objects does affect the final temperature when they are brought into thermal contact. Objects with greater mass will tend to change temperature more slowly than objects with lesser mass, due to the amount of thermal energy required to raise their temperature.


How will the composition of the objects affect the final temperature?

The composition of objects can affect the final temperature through their specific heat capacities, which determine how much heat energy is needed to raise their temperature. Objects with higher specific heat capacities will require more energy to increase their temperature compared to objects with lower specific heat capacities. Additionally, the mass of the objects will also play a role in determining the final temperature, as objects with higher masses will require more heat energy to increase their temperature.


If two objects of the same mass require different amounts of heat to raise their temperatures 10 Kelvin the object have different what?

Specific heat capacities. This is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount. Objects with different specific heat capacities will require different amounts of heat to achieve the same temperature change.


How does raising the temperature of an object affect its density?

Increasing the temperature of an object generally decreases its density. This is because as the temperature rises, the particles within the object gain more kinetic energy and spread out, causing the object to expand. Conversely, lowering the temperature would usually increase the density of the object as the particles lose kinetic energy and move closer together.


Is it harder to raise the temperature of a rock than it is to raise the temperature of water?

It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.


What do you use to raise the temperature on a fish tank?

A heater can raise the temperature of a fish tank if needed


Does evaporation rais the tempeature of a liquid?

No, evaporation does not raise the temperature of a liquid. Evaporation is a cooling process where the most energetic molecules escape from the liquid surface, leaving behind molecules with lower average kinetic energy, which lowers the overall temperature of the liquid.


How will the masses of the two objects affect the final temperature?

The masses of the objects will affect the final temperature based on their specific heat capacities. If two objects with different masses and the same heat input have different specific heat capacities, the object with the lower specific heat capacity will tend to have a higher final temperature compared to the object with the higher specific heat capacity. This is because the object with the lower specific heat capacity requires less heat to raise its temperature.


What will raise mouth temperature?

Eating spicy foods, drinking hot beverages, and having a fever can raise mouth temperature.


Is specific heat the same as specific gravity?

No. Specific heat is the amount of heat required to raise 1 kg of material by 1 K at constant pressure, while specific gravity is the ratio of the material's density to a reference density (typically water).
