Answer:
The pressure exerted on the table due to the book is 200 N/m².
Explanation:
The pressure exerted on the table due to the book is 200 N/m².
The given parameters;
mass of the book, m = 400 g = 0.4 kg
dimension of the table, = 0.10m x 0.20 m.
gravitational field strength g = 10 N/kg.
The area of the table is calculated as follows;
A = 0.1 x 0.2 = 0.02 m²
The pressure exerted on the table due to the book is calculated as follows; where;
F is the force of the book due to its weight
Thus, the pressure exerted on the table due to the book is 200 N/m².
Answer:
u did not give the options to answer
If the pressure, volume, and temperature are 202650 Pa, 0.004 cubic meters, and 400.15 K. Then the number of the mole is 0.24 mol.
<h3>What is thermodynamics?</h3>
It is a branch of science that deals with heat and work transfer.
We know that the Ideal gas equation is given as
PV = nRT
Where
P = Pressure (Pa)
V = Volume (in m³)
n = Number of moles (mol)
R = universal gas constant (8.314 J⋅K⁻¹⋅mol⁻¹)
T = temperature (in K)
We have
P = 2 atm = 202.65 × 10³ Pa
V = 4 liters = 0.004 m³
T = 127 °C = 400.15 K
Then we have
Then the number of the mole will be
