Answer:

Explanation:
We can use the Ideal Gas Law — pV = nRT
Data:
V = 66.8 L
m = 77.8 g
T = 25 °C
Calculations:
(a) Moles of N₂

(b) Convert the temperature to kelvins
T = (25 + 273.15) K = 298.15 K
(c) Calculate the pressure

S waves
- The motion of the medium is perpendicular to direction of propagation of the wave
.
- They can propagate only through solids and not through gases or liquids
.
- They travel with less speed
.
P waves
- These are compression waves
.
- These waves produces a force along the direction of propagation
.
- They can propagate through solids, gases and liquids.
- P waves are smaller than s waves
.
- They travel with 60% greater speed than S waves
.
P-waves travel 60% faster than S-waves on average because the interior part of the Earth does not react the same way as the s wave and P wave.
A) I = -1, B) Sr = +2, C) K = +1, D) N = -3, E) S = -2, F) In = +3
Answer: 4 mm
Explanation: Area equals base times the height. (Side times side) So if the area is 16, then what times what equals 16? Well, 4 times 4 equals 16 and all the sides of a square are equal. So 4 millimeters would be the answer.
hope this helps
Answer:
What is nanofluids?
Nanofluids are engineered suspensions of nanometer-sized solid particles in a base fluid. Suspending small solid particles in the energy transmission fluids can improve their thermal conductivity and provides an effective and innovative way to enhance their heat transfer characteristics significantly.
How nanofluids work?
Nanofluid refers to the dispersion of metal or non-metal nano-powder into traditional heat exchange media such as water, alcohol, and oil to prepare a uniform, stable and high thermal conductivity. The traditional heat exchange medium has a low thermal conductivity and has been unable to meet the growing demand for industrial engineering heat exchange. The thermal conductivity of some metal or non-metal nanoparticles is often hundreds of times higher than that of heat-conducting media. For example, common silicon carbide nanoparticles have a thermal conductivity of 170-270 W/m•K. The researchers found that if the nanoparticles can be uniformly and stably dispersed in the heat transfer medium, the thermal conductivity of the nanoparticles will be greatly improved.
