calculate the quantity of hear required to raise temperature of 1g of ice from _10c°?
To calculate the heat required to raise the temperature of 1g of ice from -10°C, you'll need to consider the specific heat capacity of ice and the heat equation.
The specific heat capacity of ice is approximately 2.09 Joules per gram per degree Celsius (J/g°C). This represents the amount of heat energy required to raise the temperature of 1 gram of ice by 1 degree Celsius.
The heat equation is:
Q = m * c * ΔT
where:
Q = heat energy (in Joules)
m = mass of the substance (in grams)
c = specific heat capacity of the substance (in J/g°C)
ΔT = change in temperature (in °C)
In this case, your mass (m) is 1g and the change in temperature (ΔT) is the final temperature minus the initial temperature. Let's assume the final temperature is 0°C.
ΔT = 0°C - (-10°C)
ΔT = 0°C + 10°C
ΔT = 10°C
Now we can calculate the heat required using the equation:
Q = 1g * 2.09 J/g°C * 10°C
Q = 20.9 Joules
Therefore, you would need 20.9 Joules of heat energy to raise the temperature of 1g of ice from -10°C to 0°C.
