Answer:
2500 Calories IS REQUIRED TO HEAT 50 g OF WATER FROM 25 C TO 75 C
Explanation:
Specific heat of water = 1 cal/gC
Mass = 50 g
Temperature change = 75 C - 25 C = 50 C
How many calories are required to heat the 50 g of water?
Heat = mass * specific heat * temperature change
Heat = 50 * 1 * 50
Heat = 2500 Calories
In other words, 2500 calories is required to heat 50 g of water from 25 C to 75 C.
