Question

The lab procedure involves several factors, listed below. Some were variable and some were constant. Label each factor below V for variable or C for constant.

__ mass of the water in the calorimeter
__ mass of the metal
__change in temperature of the water
__change in temperature of the metal
__volume of water in calorimeter
__calorimeter pressure
__specific heat of water

Answer 1

Answer: V, V, V, V, C, C, C, Done

Explanation: correct on edge

Answer 2

V - mass of the water in the calorimeter

V - mass of the metal

V - change in temperature of the water

V - change in temperature of the metal

C - volume of water in calorimeter

C - calorimeter pressure

C - specific heat of water

Explanation :

Variables : It is a factor that changes during the experiment or calculation.

Constant : It is a factor that does not change during the experiment or calculation.

In a calorimeter, the heat absorbed is equal to the heat released.

`Q_(absorbed)=Q_(released)`

As we know that,

`Q=m* c* \Delta T`

`m_1* c_1* \Delta T_1=-[m_2* c_2* \Delta T_2]`

where,

`m_1` = mass of water in calorimeter

`m_2` = mass of metal

`\Delta T_1` = change in temperature of the water

`\Delta T_2` = change in temperature of the metal

`c_1` = specific heat of water

`c_2` = specific heat of metal

From this, we conclude that the value of specific heat of water is constant while the other are variables.

The volume of water in calorimeter, calorimeter pressure is also constant.
