What is the symbol of a ion with a 22 protons, 34 neutrons, and 18 electrons
Dominik [7]
Well knowing the number of protons, you can find what the element is, which is Ti = titanium. Then to find the charge, simply subtract 22 and 18 which is +3.

Find the mass number by adding 22 and 34 = 56.

56. +3
Ti

22

This would be the correct notation in isotopic form.

Boyle's law only works when a gas is kept at a constant temperature. Experimentally this is very tricky as changes in pressure o
Lady bird [3.3K]

The heat that creates this temperature change coming from change in the internal energy of the system as per as first law of thermodynamics.

<h3>What is Boyle's law ?</h3>

A law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

As we know, Boyle's law only works when the gas is kept at a constant temperature

Here,

When volume of gases decreased, it means work done has occurred on the system, so the work done is used for raising internal energy of the gas and the other is released as the thermal energy.

So,

According to 1st law of thermodynamics,

we know  Q =  ΔU + W  i.e, change in internal energy and work done. So this is a reason. Changing temperature occurs.
