A calorimeter contains reactants and a substance to absorb the heat absorbed. The initial temperature (before the reaction) of the heat absorbent is measured and then the final temperature (after the reaction) is also measured. The absorbent's specific heat capacity and mass are also known. Given all of this data, the equation:
Q = mcΔT
To find the heat released.
<span>The answer is "D" where the number of collisions per unit area is reduced by one-half. Drawing back on the piston means the volume is increased. The pressure is reduced. There are fewer collisions when the pressure is reduced.</span>

Answer:
3.7 ×10⁴ m
Explanation:
We know that,
1 miles = 1609.34 meter
We need to find how many meters are there in 23.1 miles.
23 miles = 37175.85 m
or
23 miles = 3.7 ×10⁴ m
So, there are 3.7 ×10⁴ m in 23.1 miles.
