Answer:

32.4 K

Explanation:

Initial pressure P1= 50.0mmHg

Initial temperature T1= 540K

Final temperature T2=????

Final pressure P2= 3 mmHg

From

P1/T1= P2/T2

P1T2= P2T1

T2= P2T1/P1

T2= 3×540/50.0= 1620/50.0

T2= 32.4 K

Answer:

T_2=32.4K

Explanation:

Hello,

In this case, we use the Gay-Lussac's law which allows us to understand the pressure-temperature relationship as a directly proportional relationship:

\frac{P_1}{T_1}=\frac{P_2}{T_2}

Hence, we solve for the final temperature as shown below:

T_2=\frac{T_1P_2}{P_1}= \frac{540K*3mmHg}{50.0mmHg} \\\\T_2=32.4K

Best regards.

While a certain isotope decays, it emits photons. What kind of decay is happening?
gizmo_the_mogwai [7]
The correct answer is Gamma decay. It happens after beta and alpha decay because what's left after those two can enter a new process of gamma decay. This releases gamma rays which is a more complex term for the photons that you mentioned before. These rays can be dangerous for humans so care not to get caught in them.

Substance X has a fixed volume, and the attraction between its particles is strong. Substance Y has widely spread out particles
DedPeter [7]

Answer: X is a Solid; Y is a Gas

Explanation:

There are three (3) states of matter. They are: Solid, Liquid and Gases.

Substance X and Y, belong to the states of matter.

A Solid is a substance that retains its SIZE and SHAPE without need of a container (as opposed to a liquid or gas).

Thus, it will most likely be concluded that: substance X is a Solid; while Y is a Gas
