Determine the new temperature when the volume a gas at 1.56L and 20.0 ˚C changes to 2.02L. Please show work

Answers

Answer:

T₂ = 379.4 K

Explanation:

Given data:

Initial volume = 1.56 L

Initial temperature = 20°C (20+273 = 293 K)

Final volume = 2.02 L

Final temperature = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₂ = V₂T₁ /V₁

T₂ = 2.02 L × 293 K / 1.56 L

T₂ = 591.86 L.K / 1.56 L

T₂ = 379.4 K

Prior to the Civil War, the North had 80 percent of the _____ capacity in the United States.A. agricultural
B. political
C. manufacturing
D. military

Answers

Answer:

C. manufacturing

Explanation:

With the Independence of the Thirteen Colonies in 1776, the colonies became independent states, but united in a Federation, with republican and presidential political representation. States in the northern region concentrated on the development of industry and, to that end, needed free and salaried labor to operate the work within the factories. Prior to the secession war, the northern states had 80 percent of manufacturing capacity in the United States. The formation of the working class and the industrial bourgeoisie in the North has also produced a specific way of looking at political activity and civil rights.

The North had 80% of the manufacturing capacity in the U.S. before the Civil War. The North was filled with factories, whereas the South relied on farming and slaves to survive, they produced a lot of cotton and tobacco for example. During the Civil War as you could imagine, the North was making a lot of artillery, so its economy began to expand more to meet the demands of war.
