A given mass of air has a volume of 6.00 L at 101 kPa. At constant temperature, the pressure is decreased to 25.0 kPa. Calculate
Sidana [21]

Answer:

24.24L

Explanation:

According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;

P is the pressure

V is the volume

k is the proportionality constant

PV = k

P1V1 = P2V2

P1 and P2 are initial and final pressure respectively

V1 and V2 are the initial and final volume respectively

Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?

From the formula;

V2 = P1V1/P2

V2 = 101×6/25

V2 = 24.24L

The final volume for the gas is 24.24L

If a machine has an efficiency of 94% and you apply 574J of work, how much work do you get out of the machine
Mariana [72]
<h3>Answer:</h3>

539.56 Joules

<h3>Explanation:</h3>
  • Efficiency of a machine is the ratio of work output to work input expressed as a percentage.
  • Efficiency = (work output/work input) × 100%
  • Efficiency of a machine is not 100% because so energy is lost due to friction of the moving parts and also as heat.

In this case;

Efficiency = 94%

Work input = 574 Joules

Therefore, Assuming work output is x

94% = (x/574 J) × 100%

0.94 = (x/574 J)

<h3>x = 539.56 J</h3>

Thus, you get work of 539.56 J from the machine

Which term best represents a tile floor without any overlapping or gaps?
Sindrei [870]

The term plane represents a tile floor without any overlapping or gaps.

A plane is a surface formed by a straight line travelling at a fixed speed in relation to another fixed point. Thus the term "plane" is the most appropriate to describe a tile floor without any overlaps or gaps. A plane is referred to as a two-dimensional surface with three defined points that extend forever. Tessellation is the technique that results in no overlaps or gaps in a plane. Tile that overlaps does not create "crosses." reputed to be a little more structurally sound, similar to the way brick is built.
