What is the mass of an object with 2258 joules of heat absorbed?
BaileyNewellgp1709
It could be almost anything. The relationship is:
heat = mass x specific heat x temperature change
So, if you know any three of these variables, you can calculate the fourth one.

Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
What is the standard unit of heat?
Standard units of heat is Joules.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What is the change in internal energy if 20 joules of heat is released from a system and the system does 50 joules of work on the surroundings?
-70 Joules
How many amps in 200 joules?
200 joules of any other type of energy can be converted to 200 joules of heat.
When heat is absorbed by an object the speed of the particles in an object is?
increased.
When heat is absorbed by an object the speed of the particles in the object is?
increased.
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
A sample of H20 with a mass of 46.0 grams has a temperature of 100 c How many joules of energy are necessary to boil the water?
The heat of vaporization is about 2258 joules/gram46 x 2258 = 103,868 J ~ 103.9 kJ(Using the rounded value 2260 joules per gram, about 104 kJ)it is already at boiling point so in theory zero energy is required.I think the question is asking what energy is required to free the water from its liquid state to the vapour state.At 101325Pa, (1 atmosphere in old money), the latent heat of evaporation of water is 2256.7 J/g.So 2256.7 * 46 = 103808 Joules
What is heat absorption?
As Heat reaches an object it can be absorbed in the same manner as a sponge
What heat absorption?
As Heat reaches an object it can be absorbed in the same manner as a sponge
What is absorbing heat?
Heat Absorption As heat energy reaches an object, it can be absorbed, in a similar manner to the way sponges absorb water. Heat enters an object, warming it. The longer the object is exposed to the heat source, the more heat that it absorbs.

Why 2 objects at the same temperature will have different amounts of energy if one has a larger mass?
All objects have a specific heat capacity, the amount of energy it takes to increase the temperature of one gram of the object by one degree centigrade. Therefore, if an object has a specific heat capacity of say, 500 joules, and you wanted to heat 3 grams of that object by 1 degree, you would need 1500 joules of energy. But if you put that 1500 joules of energy into only 1 gram of the object, you would heat it by 3 degrees.
What happens when light hits an object it cannot pass through?
If the light can not pass through a object it is opaque . The light will reflect or be absorbed by the object.
When light is absorbed by an object does the lights energy just disappear?
It turns into heat
What is the total number of joules absorbed by 65.0g of water when the temperature of the water is raised from 25.0 to 40.0?
What is the total number of Joules of heat absorbed by 65.00 grams of water when the temperature of th water is raised from 25.00 C to 40.00 C
