how much heat is absorbed by contacting 10 grams of 100 degree C steam by a students hand.
To calculate the amount of heat absorbed by the student's hand when it contacts 10 grams of 100°C steam, you can use the specific heat capacity formula:
Q = m * c * ΔT
Where:
Q is the amount of heat absorbed or released (in Joules),
m is the mass of the substance (in grams),
c is the specific heat capacity of the substance (in J/g°C), and
ΔT is the change in temperature (in °C).
First, you need to determine the specific heat capacity of water. The specific heat capacity of water is approximately 4.18 J/g°C.
Next, calculate the change in temperature (ΔT) that occurs when the steam comes in contact with the student's hand. Assuming the student's hand is at a lower temperature, let's assume the steam temperature decreases to the temperature of the hand.
Finally, plug in the values into the formula to get the amount of heat absorbed:
Q = 10 g * 4.18 J/g°C * ΔT
Please note that without the specific value for ΔT (change in temperature), it's not possible to provide an exact answer.
