∙ 15y agoThe formula for specific heat is specific heat = energy/mass * change in temperature. Assuming the aluminum measure 5.5 *10 *10 cm, that gives a total mass of 1.48 kg, and a total energy requirement of 3108 Joules.

∙ 11y agoOkay so we have the basic energy equation:
Q = m * Cp * dT
where Q = energy (Joules)
m = mass (grams)
Cp = heat capacity (J/g.C)
dT = change in temperature ( C)
here we have
Q = 216 J
Cp = 0.90 J/g.C
dT = 20C
so using the equation we find that:
12g

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
The amount of heat energy required to raise the temperature of a unit mass of a material one degree is?
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
The amount of heat required to raise the temperature of 1 gram of water 1 degree Celsius is called?
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
Why is water hard to heat?
Because the evaporation of water carries heat away from the fire. Water has a high specific heat capacity. This is a measurement of the amount of energy required to cause a unit volume of a material to increase by a unit temperature. As such you must add a lot of energy to water to cause a small increase in temperature. For example to increase the temperature of 1 litre of water by 1 degrees C, you must add 4181.3 joules of energy.
What are the two physical properties that change with temperature?
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
Will concrete brick aluminum or copper take most energy to increase its temperature?
Whichever of them has the lowest specific heat capacity will take the least energy to raise its temperature, and whichever has the highest specific heat capacity will take the most energy.
Aluminum has a specific heat of 0.900 J/g·°C. How much energy is required to raise the temperature of 140. g of aluminum from 10.0°C to 232.0°C ---kJ?

What means that a large amount of energy is required to change the waters temperature?
Specific heat
How much heat energy is required to raise the temperature of 0.365 of copper from 23.0 to 60.0 The specific heat of copper is 0.0920?
How much heat energy is required to raise the temperature of 0.358 of copper from 23.0 to 60.0 ? The specific heat of copper is 0.0920
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
How much energy is required to raise the temperature of 3 kg of aluminum from 18C to 23C?
13,455 J
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
