Answer:
energy from a source that is not depleted when used, such as wind or solar power.
Explanation:
Answer:
20.5 torr
Explanation:
Given parameters:
Volume of tank = 15L
Pressure of tank = 8.2 x 10⁴torr
Volume of empty chamber = 6.0 x 10⁴L
Unknown:
New pressure of the gas in this chamber = ?
Solution:
To solve this problem, a good knowledge of the gas law will suffice here. Since pressure and volume relationships are under consideration, the Boyle's law is the proper gas law to apply.
Boyle's law states that "at constant temperature, the volume of fixed mass of gas is inversely proportional to the pressure of the gas".
Mathematically;
(Pressure x volume) of tank = (Pressure x volume ) of empty chamber
15 x 8.2 x 10⁴ = Pressure of empty chamber x 6 x 10⁴
Pressure of empty chamber = 20.5 torr
Answer:
Increases
Explanation:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions.
Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms
