the glass allows short wave lengths of radiation to enter, but reduces the amount of long-wave length radiation that escapes
It means that the information that you have been given is so accurate as to be unable to be mistaken or misunderstood. So therefore that information is clear. Glass is also clear and objects on the other side of that glass cannot be mistaken. So the play on the word clear is used to say that, It's as clear as glass!
Usually glass.
In glass greenhouses, sunlight enters through the transparent glass and warms the interior surfaces, such as plants and soil. These surfaces then emit heat in the form of infrared radiation, which is trapped inside the greenhouse due to the glass, preventing it from escaping. This phenomenon, known as the greenhouse effect, leads to higher temperatures inside the greenhouse compared to the outside environment, creating a warm microclimate that is ideal for plant growth.
The density of clear float glass, according to Pilkington Ltd., its original manufacturer, is 2.5 g.cm-3.
The term "greenhouse" refers to the color green, which is commonly associated with plants and nature. The design of a greenhouse typically includes glass or transparent materials that allow sunlight to enter, promoting plant growth. While other colors could theoretically be used, "greenhouse" has become the standard term due to its connection to gardening and the cultivation of green plants. The name reflects the primary purpose of the structure: to create an environment conducive to growing greenery.
The primary function of the clear glass in a greenhouse is to allow sunlight to enter, providing essential light for photosynthesis, which is crucial for plant growth. Additionally, the glass helps to trap heat, creating a warmer microclimate that protects plants from cold temperatures. This controlled environment promotes optimal growing conditions year-round.
The orientation of the sheets of glass in a greenhouse (top to bottom, inside to outside) do not change its function.
Glass allows sunlight to enter the greenhouse, providing plants with the necessary energy for photosynthesis. Glass is transparent, allowing for a clear view of the inside of the greenhouse and facilitating monitoring and maintenance of plants. Glass is durable and can withstand various weather conditions, providing a long-lasting structural material for a greenhouse.
Greenhouse plastic is a type of clear covering for a greenhouse that can be used as a cheap and safe alternative to glass. The website 'Do It Yourself' offers a useful introduction to this type of covering and what it can do.
Replacement glass for a greenhouse can typically be purchased from greenhouse supply stores, online retailers specializing in greenhouse parts, or directly from the greenhouse manufacturer if known. It is important to accurately measure the dimensions of the glass needed to ensure a proper fit.
When you talk about the greenhouse affect we are referring to the increase in the temperature of the atmosphere as a result of heat from the sun being trapped by the layer of carbon dioxide in the atmosphere. This is analogous to a greenhouse that traps heat inside with glass or some type of clear plastic.
Glass mostly. A greenhouse would need sunlight.
You can construct a green house by building a frame based on the size you need and covering it in heavy duty clear plastic or glass.
The glass or plastic walls of a greenhouse represent greenhouse gases in the atmosphere by trapping heat energy inside, much like how greenhouse gases in the Earth's atmosphere trap heat.
mostly glass
Generally clear glass is transparent.
Sunlight passes through the glass of a greenhouse and heats up the interior surfaces and objects. This heat is then trapped inside the greenhouse due to the glass barrier, preventing it from escaping. This process is known as the greenhouse effect, which allows the greenhouse to stay warm even when it is cold outside.
