Answer: vvvv
Step-by-step explanation:
To calculate the amount of heat required to raise the temperature of a substance, we can use the following formula:
Q = m * c * ΔT
Where:
Q = the amount of heat required (in Joules)
m = the mass of the substance (in grams)
c = the specific heat of the substance (in J/g C)
ΔT = the change in temperature (in Celsius)
In this case, we want to find the amount of heat required to raise the temperature of 47.5g of Al from 25°C to 62°C, so:
m = 47.5g
c = 0.900 J/g C
ΔT = (62°C - 25°C) = 37°C
Plugging these values into the formula, we get:
Q = 47.5g * 0.900 J/g C * 37°C
Q = 1,321.25 Joules
Therefore, the number of calories required for 47.5g of Al to go from 25°C to 62°C is 315.50 calories, since there are 4.184 Joules in one calorie:
315.50 calories = 1,321.25 Joules / 4.184 Joules/calorie
