The amount of heat required to raise the temperature is 706.05J.
To find the answer, we need to know more about the specific heat capacity.
<h3>How to find the heat required to raise the temperature?</h3>
- Specific heat can be defined as, the amount of heat needed to increase a substance's temperature by one degree for every gram.
- We have the expression for amount of heat required to raise the temperature from T1 to T2 as,
Q=msΔT
- We have given with the following values,
- Thus, the amount of heat required to raise the temperature is,
Thus, we can conclude that, the amount of heat required to raise the temperature is 706.05J.

Answer:
The sound intensity that the other student measure, I₂ is expected to be;
A) 6.2 × 10⁻⁸ W/m²
Explanation:
The measure of sound intensity is given by the following formula;
Where;
I = The intensity
R = The radius
P = The power of the sound
Whereby we have;
The distance of the two people talking, R₁ = 3.0 m
The measure of the sound intensity, I₁ = 1.1 × 10⁻⁷ W/m² (from an online source)
The distance of the other student from the two people talking, R₂ = 4.0 m
Therefore, the estimate of the sound intensity, I₂, is given as follows;
I₂ = 6.1875 × 10⁻⁸ W/m²
∴ The sound intensity that the other student measure, I₂ ≈ 6.2 × 10⁻⁸ W/m²
