Answer:
Start with the temperature in Fahrenheit (e.g., 100 degrees).
Subtract 30 from this figure (e.g., 100 - 30 = 70).
Divide your answer by 2 (e.g., 70 / 2 = 35).
Answer:
Explanation:
Hello,
In this case, the relationship between the mass, heat, temperature and heat capacity id given by:
In such a way, the temperature change results:
Clearly it is a positive change which means the temperature increases as heat is added.
Regards.
Answer:
0.394 atm
Explanation:
Mathematically, when we increase the pressure of a gas, we are increasing its concentration and when we decrease the pressure, we are decreasing its concentration.l at same temperature
What this means is that pressure and concentration are directly proportional.
Representing concentration by c and pressure by p, we have;
P1/C1 = P2/C2
From the question;
P1 = 0.719 atm
P2 = ?
C1 = 429.7 ppm
C2 = 235.3 ppm
Now, we can rewrite the equation to be;
P1C2/C1 = P2
Substituting the values we have;
0.719 * 235.3/429.7 = 0.394 atm
