Answer : The time required is, 16.1 minutes.
Explanation :
First we have to calculate the amount of heat required to increase the temperature is:
where,
Q = amount of heat required = ?
m = mass
= density of air =
V = volume of air
C = specific heat of air =
= change in temperature =
Now put all the given values in above formula, we get:
Now we have to calculate the time required.
Formula used :
where,
t = time required = ?
Q = amount of heat required =
P = power = 1500 W
Now put all the given values in above formula, we get:
Thus, the time required is, 16.1 minutes.
Answer:
you plug in and turn on the popper, and then the hot air begins to rise in the popper while cooler air falls. As hot air circulates past the popcorn kernels and so the kernels absorb the hear

When the metal spoon comes in contact with the hot soup, heat transfer from hot soup to the spoon because of difference in temperature of the two. The kind of heat transfer represented here is conduction. In conduction, heat is transferred from a region of higher temperature to a region of lower temperature when there is a physical contact between the two.
