Question

A piece of stainless steel weighing 1.55 g absorbs 141 J of heat energy when its temperature increases by 178oC. What is the specific heat of stainless steel?

Answer 1

Answer:

= 0.551J/(g°C)

Explanation:

Specific heat is the amount of heat to required to raise the temperature of 1 gram substance to 1° C

The formula

C = q / m × ΔT ______ (1)

where ,

C = specific heat

q = heat

m = mass

ΔT = change in temperature

mass of the stainless steel is m = 1.55g

heat of the stainless steel is q = 141 J

the change in temperature is ΔT = 178°C

substitute all the value in the equation (1)

$C = \frac{141}{1.55 \times 178 } \\\\= 0.511J /(g^\circ C)$

Answer 2

Answer: The answer is 38,901.9(J/g°C)

Explanation:

Step one: given

mass m =1.55g

Heat capacity c= 141 joules

Change in temperature ΔT=178°c

Step two:

Applying the formula

q=mcΔT

q=1.55*141*178

q=38,901.9(J/g°C)

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass
