Energy needed = (644 J/ kg C)(2kg)(40) = 51.5 kJ

ā 13y agoSpecific heat of glass is 0.84 J/gC. So convert 1 kg to 1000 grams for my convenience.
q = 1000 grams glass * 0.84 J/gC * (100 C - 20 C)
= 67200 Joules

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.
How much energy must be added to a 2-kg piece of wood with a specific heat of 1760 JkgoC to increase its temperature from 10oC to 50oC?
140,800 j
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
How much energy must be added to 1 kilogram piece of aluminum with a specific heat of 900 J to increase its temperature from 20 degrees Celsius to 100 degrees Celsius?
90,000
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?
10,400 J
What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
How much energy must be added to a 1-kg piece of granite with a specific heat of 600 J/(kgĀ°C) to increase its temperature from 20Ā° C to 100Ā° C?
48,000 J
What happens to temperature when energy is added as heat?
Either the temperature will increase, or it will remain the same. In the latter case, there is a phase change, as when ice melts.
What happens to molecules as energy is added and the temperature increases?
what happens to molecules as energy is added the temperature increses

How the temperature of water changes when sugar is added to it.?
The temperature increase a bit.
How much energy must be added to an 2 kg piece of wood with a speific heat of 1760 j to increase it's temperature from 10 C to 50 C?
Specific heat is the amount of energy required to raise the temperature of one gram of a substance one degree celsius. Therefore the answer will be: 1760 * 2000 * 40 = 140,800,000
