Question

The temperature of a piece of metal was 32°C. It was then lowered into a glass of

hot water and the temperature of the piece of metal rose to 36°С. Find the
percentage increase in the temperature of the piece of metal.​

Answer 1

12.5%

Explanation:

Given that,

Initial temperature of a piece of metal = 32°C

Final temperature of the piece of metal = 36°С

We need to find the percentage increase in the temperature of the piece of metal.​ The percentage increase in any value is given by the relation as follows :

`\%=\frac{|\text{final value-initial value}|}{\text{initial value}}* 100\\\\=(36-32)/(32)* 100\\\\=12.5\%`

So, the required percentage increase in the temperature of the piece of metal is equal to 12.5%.
