How many calories are required to raise the temperature of 250.0g of mercury 52 Celsius? The specific heat of mercury= 0.033 cal/g celsius
look at the units
250g * 52°C * 0.033cal/(g °C) = 429 cal
To calculate the amount of calories required to raise the temperature of a substance, you can use the formula:
q = m * c * ΔT
where:
q = amount of heat/energy required (in calories)
m = mass of the substance (in grams)
c = specific heat of the substance (in cal/g°C)
ΔT = change in temperature (in °C)
In this case, we have:
m = 250.0 g
c = 0.033 cal/g°C
ΔT = 52°C
Substituting these values into the formula, we get:
q = 250.0 g * 0.033 cal/g°C * 52°C
Calculating this expression gives us:
q = 429.0 cal
Therefore, it would require 429.0 calories of heat to raise the temperature of 250.0 grams of mercury by 52°C.
To find out how many calories are required to raise the temperature of mercury, you can use the formula:
Q = mcΔT
Where:
Q = heat energy required (in calories)
m = mass of the substance (in grams)
c = specific heat of the substance (in cal/g °C)
ΔT = change in temperature (in °C)
Let's plug in the given values into the formula:
m = 250.0 g
c = 0.033 cal/g °C
ΔT = 52 °C
Q = (250.0 g) * (0.033 cal/g °C) * (52 °C)
Q = 429.0 cal
Therefore, it would require 429.0 calories of heat energy to raise the temperature of 250.0g of mercury by 52 Celsius.
