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?
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.
To calculate the amount of energy transferred, you can use the formula:
q = m * c * ΔT
Where:
q = amount of energy transferred (in calories or kcal)
m = mass of the substance (in grams)
c = specific heat capacity of the substance (in cal/g * °C)
ΔT = change in temperature (in °C)
Given:
m = 3.00 g
c = 4.9 cal/g * °C
ΔT = 130 °C - 102 °C = 28 °C
Substituting these values into the formula:
q = 3.00 g * 4.9 cal/g * °C * 28 °C
Calculating this:
q = 411.6 cal
To convert from calories to kilocalories (Kcal), divide the value by 1000:
q = 411.6 cal / 1000
q ≈ 0.412 Kcal
Therefore, the amount of energy transferred is approximately 0.412 Kcal.
