<h2>Answer: faster </h2>
The speed of sound varies depending on the medium through which the sound waves travel. In addition, it varies with changes in the temperature of the medium. This is because an <u>increase in temperature means that the frequency of interactions between the particles that transport the vibration increases</u>, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.
So, if we want <u>the speed of sound in a gas to increase</u>, the<u> temperature</u> of that gas must <u>increase</u>, as well.
For example, the higher the air temperature, the greater the velocity of propagation. Experiments have shown that the speed of sound in air increases for every
increase in temperature.
Therefore:
<h2>The speed of sound will be faster than in December</h2>Explanation :
It is given that,
BMR i.e basal metabolic rate is 88 kcal/hr. So, BMR in watts is converted by the following :
We know that, 1 kilocalorie = 4184 joules
So,
J/sec is nothing but watts.
So,
and
So, it can be seen that the body can accommodate a modes amount of activity in hot weather but strenuous activity would increase the metabolic rate above the body's ability to remove heat.
