Answer:
The new temperature is 1596 C.
Explanation:
Charles's Law indicates that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases.
Statistically, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio that exists between the volume and the temperature will always have the same value:
Being an initial state 1 and a final state 2, it is fulfilled:
In this case:
- V1= 25 L
- T1= 350 C= 623 K (being 0 C= 273 K)
- V2= 75 L
- T2= ?
Replacing:
Solving:
T2= 1869 K= 1596 C
<u><em>The new temperature is 1596 C.</em></u>
A calorimeter is just an insulated container which contains the sample. You combust the sample inside the calorimeter, then you measure the temperature with respect to time. Make sure to stir constantly. Thus, you need a thermometer and a stirrer. The coffee cup calorimeter is labelled as shown in the picture attached. The goal of this experiment is to determine the specific heat capacity.
