assume the specific heat capacity of water is 4.25lgk or 4200kj how many Joule is required to raise the temperature of 500g of copper 400jkg
To calculate the amount of energy required to raise the temperature of a substance, you can use the formula:
Energy = mass x specific heat capacity x temperature change.
Given:
Mass of copper (m) = 500g = 0.5 kg
Specific heat capacity of water (c) = 400 J/(kg°C)
Temperature change (ΔT) = 400°C
Plugging in these values into the formula:
Energy = 0.5kg x 400 J/(kg°C) x 400°C
Energy = 0.5kg x 400 J/kg x 400°C
Now we solve:
Energy = 0.5 x 400 x 400
Energy = 80,000 J
Thus, 80,000 Joules of energy are required to raise the temperature of 500g of copper by 400°C.
To calculate the amount of energy required to raise the temperature of a substance, we can use the specific heat equation:
Q = mcΔT
Where:
Q is the amount of energy transferred (in joules),
m is the mass of the substance (in grams),
c is the specific heat capacity of the substance (in J/g°C),
ΔT is the change in temperature (in °C).
First, let's convert the mass of copper from grams to kilograms:
500 g = 500/1000 = 0.5 kg
Now, substituting the given values into the equation, we have:
Q = (0.5 kg) × (400 J/kg) × ΔT
To find the amount of energy required, we need to know the change in temperature (ΔT). However, it is not provided in the question. Please provide the change in temperature to calculate the answer accurately.
