0 Kelvin is the temperature where the is no kinetic energy, so the answer is 0.
Answer:
P₂ = 0.6406 atm
Explanation:
Given data:
Initial volume = 24.0 L
Initial pressure = 1.00 atm
Initial temperature = 203.0 K
Final temperature = 298.0 K
Final volume = 55.0 L
Final pressure = ?
Solution:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm × 24.0 L × 298.0 K / 203.0 K × 55.0 L
P₂ = 7152 atm .L. K / 11165 K.L
P₂ = 0.6406 atm
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
Thus we will include four significant figures in answer because 7152 have four significant figure.
Answer:
19
Explanation:
1240.64/64
This is a simple division that can easily be evaluated using any form of calculator.
Here, the main challenge is in expressing the answer in the proper number of significant figure.
The approach here is to express the answer to the which is least precise. This is usually the number with the lower significant values.
Here, 64 has two significant figures and it is of a lower rank. Our answer should be expressed this way:
= 19.385 = 19
Answer:
1)They breathe to air
2)They need nutrition to live
3)Their body is made up of cells
4)All living things respond to stimuli.
