How much energy in joules does it take to raise the temperature of 255g of water by 12.5 C?
pls help!
energy = mass x specific heat x temperataure change.
To calculate the energy required to raise the temperature of a substance, you can use the specific heat capacity equation:
Q = m * c * ΔT
Where:
Q is the energy required (in joules)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in joules per gram per degree Celsius)
ΔT is the change in temperature (in degrees Celsius)
For water, the specific heat capacity is approximately 4.18 J/g°C.
Given:
m = 255g
ΔT = 12.5°C
c = 4.18 J/g°C
Now, substitute the given values into the formula:
Q = (255g) * (4.18 J/g°C) * (12.5°C)
Q = 13,362.375 J
Therefore, it takes approximately 13,362.375 joules of energy to raise the temperature of 255 grams of water by 12.5 degrees Celsius.
To calculate the energy required to raise the temperature of a substance, we use the formula:
Energy = mass * specific heat capacity * change in temperature
For water, the specific heat capacity is approximately 4.18 J/g°C.
Given:
Mass = 255g
Change in temperature = 12.5°C
Now, let's substitute these values into the formula:
Energy = 255g * 4.18 J/g°C * 12.5°C
First, calculate the product of mass and specific heat capacity:
255g * 4.18 J/g°C = 1065.9 J/°C
Now, multiply this result by the change in temperature:
1065.9 J/°C * 12.5°C = 13,324.375 J
Therefore, it takes approximately 13,324.375 joules of energy to raise the temperature of 255g of water by 12.5°C.
energy = specific heat * temperature change
