Answer:9172.8j
Explanation:
Mass in kg x change in temp x quantity of heat
0.084×26×4200
=9172.8j
Answer:
3.40x10¹⁰ grams
Explanation:
First we<u> convert 5.25x10³² atoms to moles</u>, using <em>Avogadro's number</em>:
5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol
Then we<u> convert K moles to grams</u>, using its <em>molar mass</em>:
88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g
So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.
The main purpose of the turbine in the turbojet engine is to
drive the compressor.Answer: A) or the first option.
Answer:
435.38 L
Explanation:
From the question,
Applying ideal gas equation,
PV = nRT................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.
Since Temperature and Pressure were constant,
V ∝ n
V/n = V'/n'.................... Equation 2
Where V and V' = the initial and final Volume of Ar respectively, n and n' = the initial and final moles of Ar respectively
make V' the subject of the equation
V' = Vn'/n............... Equation 3
Given: V = 100 L, n = 3.25 mol, n' = 14.15
Substitute into equation 3
V' = (100×14.14)/3.25
V' = 435.38 L
The cars are hanging from cables so that there is presence of more medium of propagation to make it look real.
<h3>What is a Blast wave?</h3>
This is referred to as a violent propagating disturbance, produced by an explosion in air.
Hanging the cars in the air will ensure an accurate description of the effect of the blast wave on them.
