The correct option is this: THIS IS THE DEMONSTRATION OF BOYLE'S LAW. AS THE VOLUME INCREASES, THE PRESSURE DECREASES AND THE MARSHMALLOW WILL GROW LARGER.
Boyle's law states that the volume of a gas is inversely proportional to the pressure of the gas at constant temperature. The law explains the relationship between the volume and pressure of a gas at constant temperature.
Answer is B! Hope you have a good day
Answer:
P= 168258.30696 Pa
Explanation:
Given that
Mass of water vapor m = 19.00 g
Volume of water vapor V = 2.00 L
Temperature of water vapor is T = 111°C
= 384K
Molar mass of water is M = 18.0148 g/mol
Number of moles are
n = m/M
= (1.90 g)/(18.0148 g/mol)
= 0.1054 mol
Pressure inside the container is
P= nRT/V
P= 168258.30696 Pa
The concept related to this exercise to solve this problem is the ideal Gas law which establishes
P= Pressure
V= Volume
n = Number of moles
R= Gas ideal Constant
T= Temperature
Our values are given as,
From the ideal gas equation then we rearrange the equation to obtain the number of moles, then
By definition the molecular mass (n) is expressed in terms of the mass and molecular weight therefore
Therefore the mass of the helium in the blimp is 968.327Kg
here we know that the speed of the signal is same as the speed of light
so here we will have
the altitude of the airplane is given as
now we know that time taken by the signal to reach the control tower is given as
now it is given as
so above is the time taken by the signal to reach the control tower
