Answer: Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume. Using... Air pressure, or atmospheric pressure, is defined as the weight of air in Earth's (or another planet's) atmosphere.
Explanation:
Answer:
is time required to heat to boiling point form initial temperature.
Explanation:
Given:
initial temperature of water,
time taken to vapourize half a liter of water,
desity of water,
So, the givne mass of water,
enthalpy of vaporization of water,
specific heat of water,
Amount of heat required to raise the temperature of given water mass to 100°C:
Now the amount of heat required to vaporize 0.5 kg of water:
where:
mass of water vaporized due to boiling
Now the power rating of the boiler:
Now the time required to heat to boiling point form initial temperature:
Answer:
D
Explanation:
the 3 products of photosynthesis are glucose (sugar), oxygen and water. D just doesn't include water.
Answer: 24.1 mL
Explanation:
Initial volume V1 = 65 mL
Initial pressure P1 = 0.854 atm
Final volume of the gas V2 = ?
Final pressure of the gas P2 = 2.3 atm
Since, pressure and volume are involved while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
0.854 atm x 65 mL = 2.3 atm x V2
55.51 atm mL = 2.3 atm x V2
V2 = (55.51 atm mL / 2.3 atm)
V2 = 24.1 mL
Thus, the final volume of the gas will be
24.1 mL
