Keisha finds instructions for a demonstration on gas laws. 1. place a small marshmallow in a large plastic syringe. 2. cap the syringe tightly. 3. pull the plunger back to double the volume of gas in the syringe. which best describes the purpose and outcome of the demonstration? this is a demonstration of charles’s law. as the volume increases, the temperature decreases, and the marshmallow will freeze. this is a demonstration of charles’s law. as the volume increases, the temperature increases, and the marshmallow will melt. this is a demonstration of boyle’s law. as the volume increases, the pressure decreases, and the marshmallow will grow larger. this is a demonstration of boyle’s law. as the volume increases, the pressure increases, and the marshmallow will shrink.

In a thunderstorm, charge builds up on the water droplets or ice crystals in a cloud. thus, the charge can be considered to be distributed uniformly throughout the cloud. for the purposes of this problem, take the cloud to be a sphere of diameter 1.00 kilometer. the point of this problem is to estimate the maximum amount of charge that this cloud can contain, assuming that the charge builds up until the electric field at the surface of the cloud reaches the value at which the surrounding air breaks down. this breakdown means that the air becomes highly ionized, enabling it to conduct the charge from the cloud to the ground or another nearby cloud. the ionized air will then emit light due to the recombination of the electrons and atoms to form excited molecules that radiate light. in addition, the large current will heat up the air, resulting in its rapid expansion. these two phenomena account for the appearance of lightning and the sound of thunder. take the breakdown electric field of air to be eb=3.00ă—106n/c. part a estimate the total charge q on the cloud when the breakdown of the surrounding air is reached. express your answer numerically, to three significant figures, using ďµ0=8.85ă—10â’12c2/(nâ‹…m2) .

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

Could someone . i have tried to solve myself but my calculation is off
