Human can produce a maximum mechanical power of 1/3 hp (horse-power).
Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)
So:
1 ph = 746 watt = 746 J/s
1/3 ph = 248.6 J/s
we're looking for the calories, so
1 joule = 0.239006 calories
So human produce a maximum mechanical power of:
248.6 J/s = 82.88 calories per second.
We're looking for the number of calories consumed in three hours, so:
82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).
The number of food calories is 895.2 food calories

Answer:
Air mass can be described as the volume of air present and the temperature of that mass of air.
Polar air masses are cold. They have less moisture content. The temperature of Maritime Polar air mass ranges from above freezing to below 70 degrees F.
Tropical air masses can be described as air masses that are warm and have a high moisture content. Temperature ranges between 70 degrees F to 90 degrees F.
