Calculate the temperature change when 500J of heat is supplied to 100g of water
Answer Details
To calculate the temperature change when a certain amount of heat is supplied to a substance, we can use the following formula:
Q = m * c * ΔT
where Q is the amount of heat supplied, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
In this problem, we are given that 500J of heat is supplied to 100g of water. We know that the specific heat capacity of water is 4.18 J/(g·°C).
So, we can substitute the values into the formula and solve for ΔT:
Q = m * c * ΔT
500J = 100g * 4.18 J/(g·°C) * ΔT
ΔT = 500J / (100g * 4.18 J/(g·°C))
ΔT = 1.2°C
Therefore, the temperature change when 500J of heat is supplied to 100g of water is 1.2°C.
In conclusion, the temperature change of a substance when heat is supplied to it depends on the specific heat capacity of the substance, the mass of the substance, and the amount of heat supplied. The formula for calculating the temperature change can be used to solve problems involving heat and temperature change.
