A58.1g sample of quartz is put into a calorimeter that contains 250.0g of water. the quartz sample starts off at 98.4°c and the temperature of the water starts off at 25.0°c. when the temperature of the water stops changing it's 27.9°c. the pressure remains constant at 1 atm. calculate the specific heat capacity of quartz according to this experiment. be sure your answer is rounded to the correct number of significant digits.

Explanation:

Given:

We have:

Assuming that heat loss is neither from any of the components before mixing nor from the mixture just after mixing. Also the container does not absorbs any heat.

Therefore,

heat gained by the water = heat lost by the quartz

    where: specific heat capacity of quartz

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
