### What is 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/k
The 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.

###### Asked in Science

### Would substances with high specific heat capacity also have high temperatures?

Specific heat capacity is the amount of energy or heat required
to raise the temperature of a unit mass of a substance by one
kelvin. So if the specific heat capacity is high then you would
require more energy or heat to raise its temperature. The specific
heat capacity does not really have anything to do with how much you
can increase an objects temperature. IT HAS TO DO WITH THE ENERGY
NEEDED TO INCREASE THE TEMPERATURE.

### What does it mean to say that material has a high or low specific heat capacity?

The specific heat capacity of a substance is the amount of
energy required to increase the temperature of a said substance 1o
K. The capacity is measured in kilojoules divided by kilogram time
degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a
substance is high, it requires a very large amount of energy to
increase the temperature, and if it has a low specific heat
capacity, the required energy will be lower.

### How many joules of energy are required to raise the temperature of 20g of aluminum from 10 degrees C to 15 degrees C?

Heat energy Q = mass x specific heat capacity x temperature
change.
Q = m*c*delta T
Q = Joules
m = kg
c (aluminum) = 895.8 J/kg
delta T = degr.C temp. change
Answer: Q = (20/1000) x 895.8 x 5 = 89.58 Joules
(Specific heat capacity of aluminum is obtained by multiplying
its specific heat of 0.214 with c of water which is 4186 J/kg =
0.214 x 4186 = 895.8 J/kg).
