the specific heat of ethanol is o.58 cal/g c
how much energy is required to heat 60.0 g of ethanol for 25 g c to 45 c
heatrequired=mass*specificheat*(45-25)
696
To calculate the amount of energy required to heat a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q = amount of energy required (in calories)
m = mass of the substance (in grams)
c = specific heat capacity of the substance (in cal/g°C)
ΔT = change in temperature (in °C)
Given:
m = 60.0 g (mass of ethanol)
c = 0.58 cal/g°C (specific heat capacity of ethanol)
ΔT = 45°C - 25°C = 20°C (change in temperature)
Substituting the given values into the formula:
Q = 60.0 g * 0.58 cal/g°C * 20°C
Q = 696 cal
Therefore, the amount of energy required to heat 60.0 g of ethanol from 25°C to 45°C is 696 calories.
