We can use the formula:
Q = m * c * ΔT
Where Q is the amount of energy transferred (in calories), m is the mass in grams, c is the specific heat in cal/g°C, and ΔT is the change in temperature in °C.
First, we need to convert the mass to grams:
m = 3.00 g
Next, we can plug in the given values and calculate the amount of energy transferred:
Q = 3.00 g * 4.9 (cal/g * °C) * (130. °C - 102. °C)
Q = 3.00 g * 4.9 (cal/g * °C) * 28. °C
Q = 411.6 cal
Finally, we can convert this to kilocalories (Kcal):
Q = 0.4116 Kcal
Therefore, the amount of energy transferred in Kcal if 3.00g toretel changes in temperature from 102. °C to 130. °C is 0.4116 Kcal.
The specific heat (heat capacity) of toretel is found to be 4.9 (cal/g * °C). What is the amount of energy transferred in in Kcal if 3.00g toretel changes in temperature from 102.
°C to 130. °C?
