q = m x C x Δt, where q is amt of heat gained or lost, C is specific heat capacity, and Δt is change in temperature.
Known:
q = 2000J
m = 4g
Δt = 5oC
Equation:
C = q/mΔt
Solution:
C = 2000J/4g5oC = 2000J/20goC = 100J/goC

What is the amount of cooling required to low the temperature of a substance through 1 degree Celsius?
To lower the temperature of 1 gram of water by 1 degree Celsius would be to remove 1 calorie.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
What substance become a liquid when his temperature is above 0 degrees Celsius?
Any substance with a melting point above this given temperature.
What is the lowest temperature that any substance can reach it?
-273 degrees celsius is considered absolute zero, meaning that -273 degrees celsius (or 0 kelvin) is the lowest possible temperature.
What is the heat capacity of wort?
The heat capacity of anything is the amount of energy required to raise the temperature of 1 g of the substance by 1 degree Celsius. You can use this fact to calculate the heat capacity of a wort.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What specific heat capacity?
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .however it obtained the unit of J/kg/kThe specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius._____________________Apex: The energy needed to change the temperature of a substance The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
What is specific heat capacity?
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
What is specifically capacity?
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .however it obtained the unit of J/kg/kThe specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius._____________________Apex: The energy needed to change the temperature of a substance The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
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.
What requires to rise 1 g of a substance 1°?
The specific heat is the amount of heat required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin.
What is the specific heat of a substance?
The amount of heat a substance can hold.
What is specific temperature?
Specific temperature is an amount of heat per unit mass required to raise the temperature by one degree Celsius.
What is the amount of heat required to raise the temperature of a substance through ten degree Celsius?
One calorie is needed to heat 1 gram of water 1 degree Celsius
What is the amount of energy needed to change the temp of a substance called?
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
What is the specific heat of an unknown substance if 2000J of energy are required to raise the temperature of 4 grams of the substance 5 degrees celsius?
Just use the definition of specific heat. Use the following formula: (energy) = (mass) x (temperature difference) x (specific heat) Replace the amounts you know, and solve for the one you don't - in this case, the specific heat.
