It can be measured in cubic units, kilometers, meters, feet, or centimeters.
Answer:
Explanation:
To solve this problem we will use the Ideal Gas Law, which forms the following formula
Where
= Pressure of Gas
= Volume of Gas
= Moles of Gas
= Constant = 0.0821 atm L/mol K
= Temperature of Gas
There are two states to consider
State 1 is given
= 0.741 atm
= 112 mL
= unknown
= 0.0821 atm L/mol K
= 300K
State 2 is based on Standard Room Temperature Pressure (STP) which are fixed values
= 1 atm
= unknown
= unknown
= 0.0821 atm L/mol K
= 273.15K
Since this is the same mass of gas it can be reasoned that the moles of gas are the same. We rearrange the Gas Law Formula to the following
We input the values and equate the formulas for both states by substituting the value of n

Power is the RATE of generating, moving, or using energy. Its unit is the WATT .
The normal reaction of the boy of mass 70 kg is 826 N.
Let us understand about normal reaction.
The force exerted by a surface on an object in contact with it which prevents the object from passing through the surface is called Normal reaction.
To calculate the normal reaction, we use the formula below.
Formula:
N = mg+m(v-u)/t.......... Equation 1
Where:
N = Normal reaction
m = Mass of the person
g = Acceleration due to gravity
v = Final Velocity
u = Initial velocity
t = Time
From the question,
Given:
m = 70 kg
v = 4 m/s
u = 0 m/s
t = 2 s
g = 9.8 m/s²
Substitute these values into equation 1
N = (70×9.8)+70(4-0)/2
N = 686+140
N = 826 N
Hence, the normal reaction of the boy is 826 N.
