Answer:
<h2>The answer is 3.2 g/L</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of cat = 400 g
volume = final volume of water - initial volume of water
volume = 125 - 100 = 25 L
The density of the cat is

We have the final answer as
<h3>3.2 g/L</h3>

Answer:
Q = 1455.12 Joules.
Explanation:
Given the following data;
Mass = 300 grams
Initial temperature = 22.3
Final temperature = 59.9°C
Specific heat capacity = 0.129 J/gºC.
To find the quantity of energy;
Where,
Q represents the heat capacity.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt represents the change in temperature.
dt = T2 - T1
dt = 59.9 - 22.3
dt = 37.6°C
Substituting the values into the equation, we have;
Q = 1455.12 Joules.
