<span>Observing a property of a substance can be done through experiments. Most of these experiments are done by a chemical reaction. A chemical reaction involves two substances interacting with each other. However, not all property of a substance can only be observed through a reaction. Like melting experiment, freezing point determination and boiling point determination, only heat is added or is removed to the substance in order to see that certain property.</span>

musickatia [10]

Answer:

T_2=335.42K=62.27^oC

Explanation:

Hello,

In this case, by using the general gas law, that allows us to understand the pressure-volume-temperature relationship as shown below:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

Thus, solving for the temperature at the end (considering absolute units of Kelvin), we obtain:

T_2=\frac{P_2V_2T_1}{P_1V_1}=\frac{1.8L*0.75atm*(25+273.15)K}{1.2L*1.0atm} \\\\T_2=335.42K=62.27^oC

Best regards.
