<u>Answer:</u> The final temperature of water is 38.5°C
<u>Explanation:</u>
To calculate the amount of heat released or absorbed, we use the equation:
where,
q = heat absorbed = 1.506 kJ = 1506 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 30 g
c = specific heat capacity of water = 4.184 Jl/g.°C
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of water is 38.5°C

Answer: The volume of the gas in the squirrel now is 0.00532 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the gas in the squirrel now is 0.00532 L
Answer:
a molecule
Explanation:
A molecule is the smallest unit quantity of a compound which can exist by itself and retain ALL the properties of the original substance.
