Understanding Heat Transfer and Temperature Change
What is the change in temperature of the water?
The change in temperature of the water is 4.78°C, which corresponds to option D. When 1,000 J of heat is added to 50 g of water, the temperature of the water increases by 4.78°C.
What is the heat transfer equation?
The heat transfer equation may be written as Q = m c ΔT, where Q is the amount of heat transmitted, m denotes mass, c denotes specific heat, and ΔT denotes the temperature difference. Heat transfer is the process by which heat is transferred from a hot item to a cold object.
The formula to calculate the change in temperature (ΔT) is: ΔT = Q / (m * c), where ΔT represents the temperature change, Q is the heat contributed, m is the substance's mass, and c is its specific heat capacity.
By plugging in the given values for the water scenario, we get: ΔT = (1000 J) / (50 g * 4.18 J/(g°C)) = 4.78°C.
1,000 J of heat is added to 50 g of water. What is the change in temperature of the water? options : 20° C 4.18°C 718°C 4.78°C
The change in temperature of the water is 4.78°C, which corresponds to option D.
