If sand has a specific-heat capacity of 835 JkgC how much energy must be added to a 2kg pile of it to increase its temperature from 40C to 50C Show your work?
To calculate the energy required to increase the temperature of the sand, you can use the specific heat capacity formula: Energy = mass x specific heat capacity x change in temperature. Plugging in the values: Energy = 2kg x 835 J/kg°C x (50°C - 40°C) = 16700 Joules. Therefore, 16700 Joules of energy must be added to the 2kg pile of sand to increase its temperature from 40°C to 50°C.
Most substances in temperature and when heat is added to them.?
Most substances increase in temperature when heat is added to them. This is due to the absorption of thermal energy, which causes the particles within the substance to move faster, leading to an increase in temperature.
When a system does work and no heat is added to the system its temperature?
remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
How much energy must be added to a 1-kg piece of granite with a specific heat of 600 J/(kg°C) to increase its temperature from 20° C to 100° C?
The change in temperature is 80°C (100°C - 20°C). The energy required to increase the temperature can be calculated using the formula: energy = mass * specific heat capacity * change in temperature. Plugging in the values, the energy required is 1 kg * 600 J/(kg°C) * 80°C = 48,000 Joules.
What happens to temperature when energy is added as heat?
When energy is added as heat, the temperature of a system increases because the particles in the system gain kinetic energy and move faster. This increase in temperature is a result of the particles vibrating or moving more rapidly, leading to a rise in the average kinetic energy of the system.
Can thermal energy be added without an increase in temperature?
No, thermal energy is entirely energy added for heat.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
The temperature of the substance will increase when thermal energy is added without changing state. This is because the thermal energy is causing the particles within the substance to move faster, resulting in an increase in temperature.
The size of a temperature increase in a substance depends primarily on?
The size of a temperature increase in a substance primarily depends on the amount of heat energy added to the substance and its specific heat capacity. The specific heat capacity determines how much energy is needed to raise the temperature of a substance by a certain amount.

What is a direct cause of a substance's temperature increase?
The direct cause of a substance's temperature increase is the input of thermal energy, typically in the form of heat. This added energy increases the kinetic energy of the substance's molecules, causing them to move faster and leading to an increase in temperature.
Most substances in temperature and when heat is added to them.?
Most substances increase in temperature when heat is added to them. This is due to the absorption of thermal energy, which causes the particles within the substance to move faster, leading to an increase in temperature.
Why does the temperature rise as heat is being added when only one phase exists?
I think that the temperature rises when heat is being added because all of the energy has nothing else to focus on so it changes the temperature. Also, adding heat would make the temperature rise.
Why the specific heat capacity of water becomes infinity when boiling water changes into steam?
Specific heat is usually defined as the amount of energy that must be added to change the temperature. Another way to define it is the ratio between the amount of energy added and the change in temperature E/m·T(with units like joules/gram·°C) When water is at the saturation point and energy is added to it, instead of increasing in temperature, the water changes phase from liquid to gas. If you put the numbers back into the definition you get something like: 1 joule added to 1 gram of water yields a change of 0 °C so Cp = 1/1∙0 = ∞.

What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
As the temperature of a gas sample increases, the kinetic energy of the gas particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in the sample. Therefore, an increase in temperature corresponds to an increase in the average kinetic energy of the gas particles in the sample.
What happens to temperature when energy is added as heat?
When energy is added as heat, the temperature of a system increases because the particles in the system gain kinetic energy and move faster. This increase in temperature is a result of the particles vibrating or moving more rapidly, leading to a rise in the average kinetic energy of the system.
