How is heat different from the temperature of a body?
Heat is the total energy of molecular motion in a substance; temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.
Why does the land lose heat more quickly at night than a body of water does?
bodies of water tend to have more object in and animals that produce their own heat. it also absorbs heat faster than land. water actually would lose heat faster if it didn't gain it faster. It's a more precarious kind of substance than earth is. but heat from the light reflecting off the moon and the fish in the water slow the temperature drop.
Which heats up faster air or soil?
The specific heat of a substance is the amount of heat energy it takes to raise the temperature of the substance 1o C. A substance with a high specific heat requires more heat to increase in temperature than a substance with a low specific heat.Air has a specific heat of about 1.005 Kj/Kg/degree C.Most soils are mostly composed of mineral particles, air and water. The specific heat of dry soil is about 0.80 Kj/kg/degree C. However, since the specific heat of water is very high (4.2 Kj/kg/degree C), soils often have a higher specific heat than air, and heat up more slowly than the air.So it ultimately depends on the amount of moisture in the soil. A bone-dry soil can heat up quicker than air, but a wet soil will take longer to heat up than the air.
Which heats up faster cement asphalt or grass?
Asphalt will absorb more heat faster than water, grass, or cement; therefore, its temperature will rise more quickly.This is due to the higher amount of light radiation that is absorbed.
Very big particles like droplets of water absorb more radiation than they scatter how does this relate to the darkness of rain clouds?
The bigger the droplets of water in a cloud the more light is absorbed. The more light absorbed the darker the cloud.
What has got more or less energy between endothermic and exothermic?
Any substance when undergoes a phase change heat is either absorbed or released The reaction in which heat is absorbed known as an endothermic reaction and in which the heat energy is released, is known as exothermic reaction. DKK
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
What are the effect of heat on a substance?
Almost all the substance respond to heat. Heat is a type of energy which is more or less absorbed by almost all matters. The vital effect that heat causes is Expansion. Due to heat 3 types of expansion takes place within substances. They are: 1) Linear expansion of heat, 2) Surface expansion of heat & 3) Volumetric expansion of heat.
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.

Will 1 liter of hot water have more or less heat energy than 2liters of hot water?
no, there is no difference
What type of reaction will absorb more energy than it releases?
Endothermic. Assuming the energy absorbed is heat. Exothermic reactions release heat, such as the oxidation of hydrogen to create water.
What is the significance of heat capacity?
The specific heat of a substance allows us to calculate the amount of heat energy required to change its temperature. Water has a specific heat nearly 11 times great than copper, therefore, water will take 11 times more energy to heat. Also water heats slowly and copper heats and cools rapidly.
Does the size of the sponge affect the amount of water absorbed?
The size of a sponge does affect the amount of water absorbed. The bigger the sponge the more water absorbed.
Is more heat absorbed by black or navy blue?
Black.
Heat never of itself flows from a cold to a hot substance?
Heat can flow from cold to hot substances. It's flow depends on the total amount of heat of the substance not on the temperature. It flows from the substance which has more heat to the substance which has less heat stored in it.
What is the relationship between specific heat and the change in temperature of a substance?
Specific heat is the amount of energy it takes to raise a unit mass of the substance by one degree Celsius. For each unit of specific heat applied to a substance its temperature will increase by a set amount.
