How does a raindrop form?
Raindrops form around a nucleus of dust or essential oils given off by the forest canopy. Water vapour at the 'dew point' needs a seed particle for it to change state from vapour to liquid state.
Differences between heat and temperature?
heat is a energy and temperature is a measurement . (of how concentrated it is)
What is the measure of the amount of heat energy in the atmosphere?
The measure of heat in a given place is called the temperature.
How can an object produce heat?
One way is if an object has, or is given energy. For example, if you turn a lamp on and leave it, it starts to get hot from the energy being given to it
The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its?
Solubility
What is 10 percent humidity?
At any given pressure and temperatire, a volume of air can hold a certain amout of water vapour before is begins to condense out (into water droplets). 10% humidity means that the amount of water vapour in the air is 10% of what the air could hold at that pressure and temperature.
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
What is the difference between a gas and a vapour?
A gas is the normal state for a material at given temperature while a vapour is made from some particles that have escaped from the liquid surface.
What is the vapor present in the air at a given temperature compared to the maximum amount that the air could hold at that temperature is called?
In the context of water vapour, it is "relative humidity".
Why do clouds form when air rises?
As air rises, it cools adiabatically. This is the result of less pressure being applied to a parcel of air as it rises in altitude (as there is less air pressing down above it). As the air cools, its capacity to suspend water vapour decreases, and it may approach one hundred percent relative humidity, also known as dew point. Dew point is the temperature at which water vapour will condense in air at a given pressure. The condensed water vapour will form clouds, which may cause precipitation.
How will show that the process of evaporation depends on the nature of the liquid?
By the measurement of the pressure vapour at a given temperature; this value is different from liquid to liquid.
How does a rain cloud appear?
when it get cold and water condencesAnswer: The hydrologic cycle puts water into the atmosphere from oceans, lakes, rivers, evapotranspiration and other sources.The water is a gas in the atmosphere at a given temperature and pressure. When the temperature cools the water starts to condense around any handy dust particle. This condenses water in very small droplets is a cloud. The water droplets collide and/or accept more condensation until they get too heavy to remain aloft on updrafts and air currents they fall as rain.In colder conditions the water vapour forms snow, sleet or hail.
Define low humidity?
High humidity means atmospheric air is saturated with more water vapour at a given temperature. Low humidity means less amount of water vapour in atmospheric air at a given temperature.
What is given out by leaves?
A green colour, water vapour and, (during the daylight), oxygen.
Why evapourate at a low pressure?
Reducing the air pressure allows the molecules to escape
Why coefficient of performance of absorption cycle is less than compression cycle?
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
When you burn fossil fuels what gas is given off?
The main gases given off when you burn fossil fuels, such as coil, oil and natural gas, are carbon dioxide and water vapour. Both are greenhouse gases, but the water vapour quickly falls out of the atmosphere.
