Astronauts are found wearing orange-colored Advanced Crew Escape Suit (ACES) while the space shuttle is ascending or entering into space. This peculiar shade of orange known as “International Orange” was chosen for safety as it is highly visible against any kind of landscape, especially in the sea.
Cool liquid from 314 K to 273 K, freeze liquid at 273 K, and cool solid to 263 K.
4.42
Because when you divide 129/29.20, you get a long string of numbers. 4.417808219178082...
So you round to the significant figure which in this case is 2 decimal places because 29.20 has 2 decimal places.
PS did you draw that car? Cuz im into drawing cars too.
Answer:
a) The work done is 10.0777 kJ
b) The water's change in internal energy is -122.1973 kJ
Explanation:
Given data:
1 mol of liquid water
T₁ = temperature = 100.9°C
P = pressure = 1 atm
Endothermic reaction
T₂ = temperature = 100°C
1 mol of water vapor
VL = volume of liquid water = 18.8 mL = 0.0188 L
VG = volume of water vapor = 30.62 L
3.25 moles of liquid water vaporizes
Q = heat added to the system = -40.7 kJ
Questions: a) Calculate the work done on or by the system, W = ?
b) Calculate the water's change in internal energy, ΔU = ?
Heat for 3.25 moles:

The work done:

The change in internal energy:

Answer:

Explanation:
Hello,
In this case, the Boyle's is mathematically defined via:

Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:

We can compute the new pressure:

Which means the pressure is increased by a factor of four.
