Question

if you were trying to heat 1g water from temperature of 5C to 6 C, how much heat would be required to do so?

Answer 1

Answer:

The heat required is 4.18 J

Explanation:

First you need to know what is specific heat capacity ,

Specific Heat Capacity : The amount of heat required to raise the temperature of 1 gram of substance by one degree  .

The specific heat capacity of water is 4.18 J/gC.

This means that to increase the temperature of 1 gram of water by one degree , 4.18 J of energy is needed.

The formula to calculate the heat is given by :

$q=mc\Delta T$

q = heat absorbed/emitted

m = mass of the substance

$\Delta T$ = Change in temperature

c = 4.18 J/gC

Here , m= 1 gram

$\Delta T$= 6 -5 = 1 degree

Put the value in the formula:

$q=mc\Delta T$

$q=1\times 4.18\times 1$

q = 4.18 J

Unit conversion :

m = gram

c = J/gram C

T  = C

q = mcT = gram x  J/gram C x C

q = J
