Question

1000 joules of heat energy is required to raise the temperature of 2kg mass of a metal plate by 10 degree celsius.Find the specific heat capacity of the metal​

Answer 1

Answer:

Answer:

50 J/kg.K is the specific heat of the metal

$\dag$Given:$\dag$

$\textsf{Heat energy required = 1000 joules}$

$\textsf{Mass of the metal plate = 2 kg}$

$\textsf{Change in temperature is = 10 ° C}$

$\dag$To find:$\dag$

$\textsf{To find the specific heat capacity of the metal}$

$\dag$Taken:$\dag$

To find the specific heat capacity of the metal use this formula:

$\boxed{H=\frac{E}{mt}}$

Where,

H = Specific heat capacity of the metal

E = Energy

m = Mass of the metal

t = Change in temperature

$\dag$Solution:$\dag$

$\bold\purple{Taken,H=\frac{E}{mt}}$

$\Rightarrow{H=\frac{1000\:joules}{2kg×10°C}}$

$\Rightarrow{H=\frac{1000\:joules}{20}}$

$\Rightarrow{H=50J/kg.K}$

$\dag$Additional information:$\dag$

First equation of motion:

$Vf=Vi+at$

Where,

Vf = Final velocity

Vi = Initial velocity

a = Acceleration

t = Time taken

Second equation of motion:

$s=ut+\frac{1}{2}at²$

Where,

s = Distance travelled

u = Initial velocity

t = Time taken

a = Acceleration

Third equation of motion:

$v²=u²+2aS$

Where,

v² = Final velocity

u² = Initial velocity

a = Acceleration

S = Displacement of the body
