Answer: The volume is 57.52 mL if the temperature if raised to 343K.
Explanation:
Given: 
= 27 mL, 
= 161 K
= ?, 
= 343 K
According to Charles law, at constant pressure the volume of an ideal gas is directly proportional to temperature.
Formula used is as follows.
Thus, we can conclude that volume is 57.52 mL if the temperature if raised to 343K.
<u>Answer:</u>
By 1700, 13 elements had been discovered and isolated by the Scientists.
Option (a)
<u>Explanation:</u>
- The copper, gold and silver are the elements which have been known from thousands of years. In the early days of 1700, the scientist discovered only 12 elements, later on one more element was discovered.
- Later in the era of 1800, the scientist research and find new elements, where they organize it methodically, according to the physical and chemical properties.
- After a long research in 1900 scientist discovered more than 80 elements.
