Answer: 
is 1155 kJ
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system=
{Work done on the system is positive as the final volume is lesser than initial volume}
w =
(1kcal=4.184 kJ)
q = +1.1 MJ = 1100 kJ (1MJ=1000kJ) {Heat absorbed by the system is positive}
Thus is 1155 kJ
Answer:
<h3>The answer is 1.28 N</h3>
Explanation:
The force acting on an object given the mass and acceleration we use the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 142 g = 0.142 kg
acceleration = 9 m/s²
We have
force = 0.142 × 9 = 1.278
We have the final answer as
<h3>1.28 N</h3>

Answer:
382mL
Explanation:
Boyle's Law P₁V₁ = P₂V₂
(0.850atm)(675mL) = (1.50atm)(V₂)
573.75 = (1.50atm)(V₂)
V₂ = 573.75/1.50
V₂ = 382.5mL = 382mL
