How does the temperature of 33.0 g of graphite change when it absorbs 350 J of thermal energy?
q = mass graphite x specific heat graphite x (Tfinal-Tinitial)
q = 350 J
mass graphite is 33.0 g
You will need to look up the specific heat graphite.
delta T is Tfinal-Tinitial and you are to solve for delta T.
To calculate the change in temperature of a substance when it absorbs thermal energy, we can use the formula:
q = mcΔT
Where:
q = thermal energy absorbed (in joules)
m = mass of the substance (in grams)
c = specific heat capacity of the substance (in J/g°C)
ΔT = change in temperature (in °C)
In this case, we are given:
q = 350 J
m = 33.0 g
The specific heat capacity of graphite is approximately 0.71 J/g°C. We can rearrange the formula to solve for ΔT:
ΔT = q / (mc)
Substituting the given values, we have:
ΔT = 350 J / (33.0 g * 0.71 J/g°C)
Calculating the right side of the equation:
ΔT = 350 J / 23.43 J/°C
ΔT ≈ 14.92 °C
Therefore, the temperature of the 33.0 g of graphite will increase by approximately 14.92 °C when it absorbs 350 J of thermal energy.
To determine how the temperature of a substance changes when it absorbs thermal energy, we can use the equation:
q = mcΔT
Where:
- q is the amount of thermal energy absorbed or released by the substance
- m is the mass of the substance
- c is the specific heat capacity of the substance
- ΔT is the change in temperature
In this case, we are given the mass of the graphite (33.0 g) and the amount of thermal energy it absorbs (350 J). However, we need to know the specific heat capacity of graphite to solve the equation.
The specific heat capacity of a substance represents the amount of thermal energy required to raise the temperature of 1 gram of the substance by 1 degree Celsius. Unfortunately, the specific heat capacity of graphite is not provided in the question. Therefore, we cannot calculate the change in temperature of the graphite without this information.
The specific heat capacity of graphite can vary depending on its purity and other factors. A commonly used average value is around 0.71 J/g°C. However, to obtain a more accurate result, it is recommended to consult reliable sources or conduct experiments to determine the specific heat capacity of the specific graphite sample in question.
