A sample of ammonia gas at 65.5°C and 524 torr has a volume of 15.31 L. What is its volume when the temperature is –15.8°C and i

ts pressure is 524 torr? 20.2 L 11.6 L 63.5 L not possible, since the volume would have to be negative 3.69 L

P=const

T=65.5+273=338.5°K

T₁=273-15.8=257.2°K

V/T=V₁/T₁

V₁=VT₁/T=

=  \frac{15.31 \times 257.2}{338.5}  = 11.6 \: l

A force of 25 newtons is exerted over an area of 50 square meters. Calculate
snow_lady [41]

Answer:

the pressure exerted in pascals is 0.5 Pa

Explanation:

The computation of the pressure exerted in pascals is shown below:

As we know that

Pressure = force ÷ area

= 25 ÷ 50

= 0.5 Pa

Hence, the pressure exerted in pascals is 0.5 Pa

We simply applied the above formula so that the correct pressure could come

grigory [225]

Answer:

B - (C , Al, P, Cl)

Explanation:

How I got this answer was by looking at my periodic table it shows you how much it contains by the Atomic number.

Atomic number on C (Carbon) is- 6

Atomic number on Al (Aluminum) is - 13

Atomic number on P (Phosphorus) is - 15

Atomic number on Cl (Chlorine) is - 17

Now it says least to greatest and the other options are wrong I did the work for you hope this helps :)) I also had this project  you didnt ask but the answer for the The Lesson are {B E M S} which as the code numbers are gonna be -7494- Im glad to help if you need more help I will give you the other answers as well :) !

Scientific process how can a casual question be answered 3 hypotheses water experiment
Vlad1618 [11]

There are 3 experiments which helps to under water evaporation system.

  • Both the temperature of the air surrounding the water and the rate of evaporation increased.
  • In the second experiment, we observed an increase in air flow around the water, and this time, the rate of evaporation increased as well.
  • In the third and final experiment, we observed an increase in the amount of light in the room, and this time, the rate of evaporation increased as well.
  • Because the kinetic energy of a substance can be measured by its temperature, increasing in the temperature or kinetic energy of the air around water will also increase the kinetic energy of the water, which will increase the rate of evaporation.
  • It's crucial to have good air flow since it drives water droplets in the air away from you, reducing the amount of humidity in the region. Because there will then be space for the evaporated air or space for the evaporated water to flow into the air, it will then be simpler for the water to really evaporate.
  • Water in the presence of sunlight is given extra energy, which increases evaporation.
