<u>Answer:</u> The final temperature of the coffee is 43.9°C
<u>Explanation:</u>
To calculate the final temperature, we use the equation:
where,
q = heat released = 
m = mass of water = 10.0 grams
C = specific heat capacity of water = 4.184 J/g°C
= final temperature = ?
= initial temperature = 20°C
Putting values in above equation, we get:
Hence, the final temperature of the coffee is 43.9°C
Answer:
35.0 kPa
Explanation:
As pressure decreases, the volume of a gas increases at a given temperature., so since the balloon got bigger, the new pressure must be less than 103kPa
Assuming the temperature does not change, use Boyles Law
P1V1 = P2V2
(103kPa) (1750L) = P2 (5150L)
P2 = (103)(1750) / 5150
No mountains in the world are increasing in size
