The volume of a gas decreases from 15.7 m3 to 11.2 m3 while the pressure changes from 1.12 atm to 1.67 atm. If the initial temperature is 245 K, what is the final temperature of the gas
Answers
The final temperature of the gas is 260.01 K.
The final temperature can be calculated by using the equation as follows:-
........(1)
Here, and
is the pressure of this gas before and after the changes.
and
is volume of this gas before and after the changes.
and
is the temperature (in degrees Kelvins) of this gas before and after the changes.
Given values:-
Substitute all the values in the equation (1) as follows:-
Hence, the final temperature of the gas is 260.60 K.

Explanation:
The data is given as follows.
= 1.12 atm,
= 1.67 atm
,
,
= ?
Therefore, calculate the final temperature using the relation as follows.
=
=
=
= 260.605 K
= 260.61 K (approx)
Thus, we can conclude that final temperature is 260.61 K.

The correct answer is option a, silicon-14
Number of electrons = 14
Number of protons = 14
Number of neutrons = 18
Since atomic number is equal to the number of protons, the atomic number of this specific silicon isotope is 14.
Also, mass number is equal to number of protons and number of neutrons. So mass number so this specific silicon isotope is 14 + 18 = 32
The name of this specific silicon isotope is silicon-14.
Silicon-14 is represented as ³²Si₁₄

The alpha decay of Radon-198 produces alpha particle and ¹⁹⁴₈₄Po.
What is alpha decay?
Alpha decay is a type of radioactive disintegration in which some unstable atomic nuclei spontaneously expel an alpha particle to dissipate excess energy.
Alpha decay of Radon-198 is shown as:
¹⁹⁸₈₆Rn → ⁴₂He + ¹⁹⁴₈₄Po
In the above decay from the parent nuclei, daughter nuclei (¹⁹⁴₈₄Po) and alpha particle (⁴₂He) is produced.
Hence daughter nuclei of the alpha decay of Radon-198 is ¹⁹⁴₈₄Po.

Final answer:
Slow receptors, which respond to stimuli over longer durations, are more likely to have a cumulative or 'summation' effect. The likelihood of this summation increases with the length of time required for the responses to decay. This mechanism plays a critical role in cognitive functions such as learning and memory.
Explanation:
In the context of neuronal signaling, when we speak about slow receptors, we are referring to those that respond to stimuli at a slower pace, often due to a longer duration of transmitter binding, and therefore have a higher likelihood of summation compared to the fast receptors.
The concept of summation refers to the cumulative effect of a series of neural responses that take time to diminish. In this case, the likelihood of summation is increased by the long period of time required for those responses to decay. Thus, the correct answer to your question would be option D) increased : long period. This is because the longer the responses take to decay, the more likely they are to accumulate or summate.
It is also important to note that this process significantly contributes to the cognitive functions of the brain, such as memory and learning by facilitating the creation of long term potentiation within neural networks.
