Q = mc(delta)T

Q = quantity of heat energy

m = mass

c = specific heat capacity different constant for each different

substance

(delta)T = difference in temperature (subtract high temp - low

temp)

### How much energy must be added to a 2kg piece of aluminum with a specific heat of 900 JkgoC to increase its temperature from 10oC to 50oC?

The equation relating heat to specific heat capacity, where the
unit quantity is in terms of mass is:
where Q is the heat put into or taken out of the substance,
m is the mass of the substance, c is the specific
heat capacity, and ΔT is the change in temperature.
Where the unit quantity is in terms of moles, the equation
relating heat to specific heat capacity (also known as molar heat
capacity) is
where Q is the heat put into or taken out of the substance,
n is the number of moles, c is the specific heat
capacity, and ΔT is the change in temperature.

### Difference between specific heat capacity and latent heat?

Specific heat capacity (equation Q=mcÃ�ï¿½T) is the
measure of the energy required in Joules to raise 1kg of a
substance by 1.0 K (numerically equivalent to 1 C)
Whereas, specific latent heat (equation Q=mL) is the
amount of energy needed to change to the state of a substance
either from solid to liquid, liquid to gas without changing its
temperature.

### What is the equation of heat?

The equation is Q=m*c*delta t. Q represents heat, usually in
calories. m represents the mass of the substance being tested. c
represents the specific heat of the substance being tested. delta t
represents the change in temperature of the substance (use a
calorimeter). Make sure that units are consistant throughout the
equation. If Q is represented in calories make sure that the
specific heat is cal/g*degrees C instead of Joules/g*degrees C.

###### Asked in Physics

### IS specific heat capacity of water using electrical method experiments less or more than the actual specific heat capacity of water?

Definitely less than the actual reading due to the heat lost to
the surrounding. The equation:
mcO = VIt
from the equation, you will know that if change in temperature,
O greater than the actual value (meaning that heat lost to the
surrounding), the specific heat capacity that you calculated from
your gradient will more than the standard reading.
P/s:
O = change in temperature (because I cannot find the
symbol for it)

###### Asked in Physics, Chemistry

### What is the equation of specific heat?

Q = mcΔT Q is the amount of heat needed to change
the temperature of a substance m is the mass of the heated
substance c is the specific heat capacity (if this is what
you're looking for, then the equation should be Q / mΔT = c
) ΔT (pronounced delta T) is the temperature
difference; the difference in temperature before and after you
applied the heat A very helpful PowerPoint:
