There is only one pressure this situation would be a "constant pressure" process. The work done by expanding gas is.
=p(delta V) = (1.5e3)(5.e3)(5.4e-5) N/m^2xm^3) N/m2xm^3= 8.1e-2 N-m ANS

Answer:

8.1x10⁸ J

A pressure constant process.

Explanation:

The gas inside the balloon is gain heat from the surroundings and its volumes increase, but the pressure remains constant. So, it's a pressure constant process.

For this thermodynamic process, the work is the pressure multiplied by the volume variation:

W = 1.5x10³ x 5.4x10⁵

W = 8.1x10⁸ J

what is the necessary condition within the hydrogen atom for balmer line photons to be absorbed by the hydrogen atom
luda_lava [24]

Explanation :

When an electron jumps from one energy level to another, the energy of atom gets changed.

If a photon gets absorbed, the electron will move to higher energy levels and then fall back to the lower energy levels. Then each time a photon will be absorbed whose energy is given by difference between the initial and final energy levels i.e

In Balmer series, the transition is from higher energy levels to n = 2.

So, the necessary condition for Balmer series is that the electron should be at first excited state or n = 2 level as shown in figure.

Why does it rain a lot?
Vaselesa [24]

Answer:

Clouds are made up of tiny water droplets. ... As more and more droplets join together they become too heavy and fall from the cloud as rain. Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

The graph shows a car's velocity over time. During which time period does the car have the greatest acceleration?
Oksana_A [137]

Answer:

Between 0 and 1 seconds (B)

Explanation:

The velocity of the car over time is represented by the line graphed here

the steeper the line, the greater change in velocity that occurred in a given time frame.

The steepest portion of the line is between 0-1 seconds, which means that the greatest rate of change occurred between 0-1 seconds.

(acceleration is the rate of change)

Add these measurements, using significant figure rules 1.0090cm + 0.02cm
Harlamova29_29 [7]

Answer:

1.03

Explanation:

0.02 has two significant decimal figures, so start by shortening 1.0090 to 2 decimal places (3 significant figures). Round up the decimal to become 1.1 and add .02 to get 1.3.
