The heat of combustion of benzene, c6h6, is –41.74 kj/g. combustion of 4.50 g of benzene causes a temperature rise of 4.50°c in a certain bomb calorimeter. what is the heat capacity of this bomb calorimeter?

Heat capacity this bomb calorimeter =  

Explanation:

Given data we have in the question:

The heat of combustion for the benzene,  (Here the negative sign depicts the release of heat and only magnitude is considered fro the heat capacity)

The mass of benzene,

The change in temperature due to the combustion,

Now, the formula for the heat capacity is given as:

Heat capacity (C) =

or

C =  

or

C =

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
