Question

A temperature of a 50 kg block increases by 15°C when 337,500 J thermal energy are added to the block. what is the block made of?​

Answer 1

Answer:

Iron

Explanation:

H = mc∅

Above equation can be used here to find the answer to the question. this equation gives us the relationship between the heat energy supplied to a material and the temperature difference that the material would go through according to its mass.

here H is the Heat energy supplied to the material. m is the mass of the material. c is the specific heat capacity of the material and ∅ is the temperature difference applied to the material. we are given that H= 337,500J , m = 50 kg and ∅ = 15 °C. so from the equation now we can calculate the value of c. after calculating c we can find the material because c is an unique value for a particular material. no two materials have the same c value.

c = 337500/(50*15)

c = 450 J/(kg°C) - Iron (google the heat capacity value to find the answer Iron)
