Answer:
hello
Explanation:
In order to determine the specific heat capacity for a particular material, we can use the following formula:
c
=
Q
m
Δ
T
, where:
Q is the given value of the energy.
m is the mass of the material.
Δ
T
is the change in temperature.
Answer and Explanation:
We are given the following data:
The mass of the block of iron is m = 2 kg.
The value of the energy is
Q
=
10
k
J

.
The change in temperature is
Δ
T
=

∘
C
=

K
=

Substituting the problem-specific values for Q, m, and
Δ
T
into the formula and simplifying it for specific heat capacity, we get:
c
