How much heat does it take to raise the temperature of 0.10 kg of gold by 25 oc?
About 322.5 Joules of heat
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
How much energy is released when 496 g of ethanol 46 g mol vapor condenses The heat of vaporization of ethanol is 38 6 kJ mol?
298 - 299
How much heat is needed to raise a 10g of water from temperature of 22 degrees Celsius 18 degrees Celsius?
to solve this we use the formula Q(heat) = mc(change in temp) so, Q=(10g)(4.19J/gC)(18-22) Q=-167.6kJ of heat.
Why does land heat unevenly?
This is due to the difference in the specific heat capacity of water and land. Water has a very high specific heat capacity. So the amount of heat required to raise its temperature is very high. That is why land heats up faster than water.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
How much heat does it take to raise the temperature of 0.10 kg of gold by 25 oc?
About 322.5 Joules of heat
How much heat does it take to raise the temperature of 0.10 kg siver by 25C?
62762.3773kg
What is the measure of how much heat will raise the temperature of 1 kg of a substance by 1 degrees c?
The specific heat of the substance.
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
How much heat would be required to raise the temperature of 17.8 g Ag by 22C?
The answer is 4,18 joule.
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
How much heat is needed to vaporize 1.25 kg of ethanol?
The heat of vaporization of ethanol is approximately 840 kJ/kg. To find the total heat required to vaporize 1.25 kg of ethanol, you can multiply the mass by the heat of vaporization: 1.25 kg * 840 kJ/kg = 1050 kJ.
Does it take different lengths of time to raise the temperature of different liquids?
Yes, it can take different lengths of time to raise the temperature of different liquids because each liquid has a specific heat capacity, which determines how much energy is needed to raise its temperature. Liquids with higher heat capacities require more energy to increase their temperature compared to liquids with lower heat capacities.
Would substances with high specific heat capacity also have high temperatures?
Not necessarily. A substance with a high specific heat capacity can absorb a lot of heat energy without a large increase in temperature. This means it can reach a high temperature if it receives enough heat, but its ability to retain heat may delay the rate at which it heats up.
How much heat is necessary to raise the temperature of a 15 g metal from 15 C to 25 C?
The answer will depend on the thermal capacity or heat capacity of the metal.
