If there is no room for the plants in your living space, you can help them get through winter by storing pots at six to seven degrees Celsius. Examine them twice a month and water them very lightly when the soil fee...
Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual vapor in the air to this fixed amount. For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 ...
The temperature dropped from -4 degrees F to -12 degrees F. How many degrees did it drop?Calculating the Temperature DropThe estimate of the hotness or coldness of any living or non-living thing is known as temperature. We can use the subtraction principle to get...
The amount of water vapor any mass of air can contain depends on the temperature of that air: The warmer the air is, the more water it can hold. A low relative humidity means that the air is dry and could hold a lot more moisture at that temperature. For example, at 20 degrees C ...
