Answer:
Heat change is -14,175 joules, Exothermic
Explanation:
We are given;
- Mass of aluminium bar as 350.0 g
- initial temperature as 70.0 °C
- Final temperature as 25 °C
We are required to determine the heat change and indicate whether endothermic or exothermic;
We know that;
Heat change = Mass of a substance × specific heat × change in temperature
In this case;
Mass of Aluminium = 350.0 g
Change in temperature = (25 - 70)
= -45° C
Specific heat of aluminium = 0.90 J/g°C
Therefore;
Heat change = 350.0 g × 0.90 J/g°C × -45°C
=-14,175 joules
The heat change is exothermic because it is a negative value, also because cooling process involves heat loss and thus an exothermic reaction.
Answer:
3.55atm
Explanation:
We will apply Boyle's law formula in solving this problem.
P1V1 = P2V2
And with values given in the question
P1=initial pressure of gas = 1.75atm
V1=initial volume of gas =7.5L
P2=final pressure of gas inside new piston in atm
V2=final volume of gas = 3.7L
We need to find the final pressure
From the equation, P1V1 = P2V2,
We make P2 subject
P2 = (P1V1) / V2
P2 = (1.75×7.5)/3.7
P2=3.55atm
Therefore, the new pressure inside the piston is 3.55atm
