Question

Calculate the specific heat of glass if 13.4 J of energy are required to heat 8.0 g of water by 2.0°C.

Answer 1

Answer:- Specific heat of glass is
`c=0.84(J)/(g.^0C)` .

Solution:- It asks to calculate the specific heat of glass when 13.4 J of heat is required to heat 8.0 g of water by 2.0 degree C.

The equation used for solving this type of problems is:

`q=mc\Delta T`

where, q is the heat energy, m is the mass, c is specific heat and
`\Delta T` is change in temperature.

From given info:

q = 13.4 J

m = 8.0 g

`\Delta T` = 2.0 degree C

c = ?

Let's plug in the values in the equation and solve it for c:

`13.4J=8.0g*c*2.0 ^0C`

On rearrangement:

`c=(13.4J)/(8.0g*2.0^0C)`

`c=0.84(J)/(g.^0C)`

So, the specific heat of glass is
`c=0.84(J)/(g.^0C)` .
