Answer:
Explanation:
According to given:
- molecular mass of glycerin,
- molecular mass of water,
- ∵Density of water is
- ∴mass of water in 316 mL,
- mass of glycerin,
- pressure of mixture,
- temperature of mixture,
<em>Upon the formation of solution the vapour pressure will be reduced since we have one component of solution as non-volatile.</em>
<u>moles of water in the given quantity:</u>
<u>moles of glycerin in the given quantity:</u>
<u>Now the mole fraction of water:</u>
<em>Since glycerin is non-volatile in nature so the vapor pressure of the resulting solution will be due to water only.</em>
Wind speed and air temperature are used to calculate a windchill factor.
<u>Explanation:</u>
<u></u>
Wind-chill factor is the reduction of body temperature due to the passing flow of lower-temperature air.
The air temperature value is always higher than the wind chill numbers. the heat index will be used if the apparent temperature is higher than the air temperature.So, Wind speed and air temperature are mainly used to calculate a windchill factor.
There are many ways, the surface loses its heat through conduction, evaporation,radiation, and convection.The rate of convection depends on the difference in temperature between the surface and the fluid surrounding the surface and the velocity of that fluid with respect to the surface. The air around the warm surface will be heated, an insulating layer of warm air forms against the surface.The layer becomes a boundary between two. As the wind speed is high the surface cools down rapidly.
Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
Explanation:
Answer:
It works by adding an engine, a transmission, car batteries, an extra strong frame in case of a crash, and much more needed things. When it races, The rubber often burns a lot, because of the high speeds that it goes, so that is why they so often change the tires. They give it a full tank of gas, which is basically like the car's idea of food and water. A NASCAR must have a trong engine to go so fast in order to win a race.
Explanation:
Just think of it like building a lego car just hot gluing the legos together and seeing if it breaks.
