VladimirAG [237]

What is the specific heat of a substance whose mass is 7 grams, if it absorbs 180 calories to go from 10 degrees Celsius to 85 degrees Celsius

Answer:

0.343cal/g°C

Explanation:

Given parameters:

Mass of substance  = 7g

Quantity of heat absorbed  = 180calories

Initial temperature  = 10°C

Final temperature  = 85°C

Unknown:

Specific heat of the substance  = ?

Solution:

To solve this problem, the specific heat of a substance is the amount of heat needed to raise the temperature of a unit mass of that substance by 1°C.

 Mathematically;

 C = \frac{Q}{m (T_{2} - T_{1} )}  

C is the specific heat

Q is the amount of heat

m is the mass

T is the temperature

1 and 2 are the initial and final states

  Now, insert the parameters and solve;

           C  = \frac{180}{7 (85 - 10)}   = 0.343cal/g°C
