Answer: 4.10 liters
Explanation:
Given that:
initial volume of gas V1 = 3.0L
initial temperature of gas T1 = 273K
new volume V2 = ?
new temperature T2 = 373K
Since, only volume and temperature are involved, apply the formula for Charle's law
V1/T1 = V2/T2
3.0L/273K = V2/373K
To get the value of Z, cross multiply
3.0L x 373K = 273K x V2
1119 = 273V2
Divide both sides by 273
1119/273 = 273V2/273
4.10L = V2
Thus, the new volume is 4.10 liters
Answer:
Sort the lab chemicals in alphabetical order for quick access.
Become familiar with the chemicals to be used, including exposure or spill hazards.
Locate the spill kits and understand how they are used.
Explanation:
There are many chemicals in a laboratory hence they should be sorted out and arranged in alphabetical order so that theory can easily be identified and located whenever they are required.
The properties of each chemical should be known especially hazards connected to exposure or spill of the chemicals.
The students should also familiarize themselves with the contents of spill kits and how they are used.
Answer:
true
