As heat energy is added to a liquid do the particles increase or decrease in movement?

As heat energy is supplied to a liquid, its temperature rises. The rise of temperature causes a rise in the kinetic energy of the particles; which happens when the speed of the particles increases.


If sand has a specific-heat capacity of 835 jkgC then how much energy must be added to a 2 kilogram pile of it to increase its temperature from 40 C to 50 C?

Q = m c ΔT Q = energy m = 2 kg c = 835 J / (kg C) ΔT = 10 C Q = 2 kg * 835 J / (kg C) * 10 C Q = 16700 J


Why do substance s expand when energy is added to them as heat?

When heat is added to a system, it increases the kinetic energy of the molecules. Increased K.E in system causes molecules to move further away from each other. This causes system to increase in volume. Significant increase in volume might not occur but at microscopic level it definitely changes.


Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?

pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.


How does volume affect temperature?

Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.

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.


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.


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.


How much energy must be added to a 1 kg piece of glass with a specific heat of 644 J kgC to increase its temperature from 20 C to 100 C?

The energy required to increase the temperature of a substance can be calculated using the formula: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values gives Q = 1kg * 644 J kgC * (100C - 20C) = 51,520 J. Therefore, 51,520 Joules of energy must be added to raise the temperature of the glass.


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 = ∞.


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 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.
