Answer:The correct answer option A.
Explanation:
Q= heat removed from the water
m= mass of the water = 80 grams
c = heat capacity of water= 4.18 J/g°C
Q = -10,032 joules -10,000 Joules
Negative sign indicates that heat was removed from the water.
Heat removed from the water of 80 gram of water is 10,032 Joules.Hence, the correct answer option A.
Standard temperature is 273 K
Standard pressure is 1 atm
We use the ideal gas equation to find out density of nitrogen gas in g/L
Ideal gas equation:
Molar mass of
Pressure = 1 atm
Temperature = 273 K
= 1.25 g/L
Therefore, density of nitrogen gas at STP is 1.25 g/L
