Explanation :

The periodic table is a type of table in which the element are systematically arranged on the basis of the atomic number.

The periodic table have the groups and periods. In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group.

Hence, 1A, 3B, and 7A are examples of group number on the periodic table.

A fire breaks out and increases the Kelvin temperature of a cylinder of compressed gas by a factor of 2.4. What is the final pre

kherson [118]

Answer:

P(final) is 2.4 times P(initial).

Explanation:

Here we can assume that the cylinder did not break and it's volume and number of moles of gas present in the cylinder remains constant.

Given the temperature increases by a factor of 2.4. Let us assume that the initial temperature be $T_{1}$ and the final temperature be $T_{2}$ .
