Question 1 (10 points) Question 1 Unsaved

How much heat is needed to raise 0.30grams of Aluminum from 30 Celcius to 150 Celcius?

(Use 0.9J/gC for the specific heat of Aluminum)

Question 1 options:

120J


32.4J


0.9J


100J

Answer 1

The answer would be the last option

Answer 2

The equation from which heat can be calculated is represented as:

q=mc\Delta T

Where, q=Heat (J)

m=mass of aluminium(g)

Delta T=Change in temperature(⁰C)

c=specific heat (J/g ⁰C)

Here ,

m=mass of aluminium(g)=0.3 g

Delta T=Change in temperature(⁰C)=150-30⁰C=120⁰C

c=0.9J/gC

Putting all the values in the above equation,

q=mc\Delta T

q=0.3×0.9×120

q=32.4 J

So, heat required will be 32.4 J.
