Question

A 2kg block of iron is given 10 kj of energy and its T° rises by 10°c what is SHC of the iron?
Please help!​

Answer 1

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

=

The change in temperature is

Δ

T

=

Substituting the problem-specific values for Q, m, and

Δ

T

into the formula and simplifying it for specific heat capacity, we get:

c
