Why do puddles disappear quicker on hot dry days than on cool dry days?
Puddles disappear quicker on hot dry days because the heat causes the water in the puddle to evaporate more quickly. The high temperature speeds up the water molecules, increasing their energy and allowing them to escape into the air more rapidly. On cool dry days, the lower temperature slows down the evaporation process, leading to puddles taking longer to dry up.
How long does it take a nuclear reactor to cool?
The time it takes to cool a nuclear reactor down varies. If a reactor has been running at nearly full power and is shut down, it takes several days to even weeks to cool it down. The size of the reactor and the "aggressiveness" of a cooling system will affect the cooldown time as well as the power levels at which the reactor was operating at before shutdown. If a reactor has been operating for some time at high power and is shut down, fission in the core stops (as it does in any shutdown). But fission products in the core are at a high level because the reactor was operating at high power. These fission products will continue to decay for some time. The decaying fission products will be creating a lot of residual heat for this extended period, too.
How long can a power plant run unmanned?
The length of time an unmanned power plant will run will vary as the type of plant (and the location). In the case of coal fired plants, the auto-loaders won't last long without someone driving the endloader to get fuel (the coal) to the front end. In the case of oil fired plants, these could run for several weeks or months without intervention if fuel supplies were set up properly. The best of these plants are highly automated and have a good service life with little intervention required. It's the steam side that gives us "maintenance" problems. Hydroelectric plants would be a top contender. They can run for weeks and even months without help. Hoover Dam would only last a few weeks owing to clogging of the generator coolers by organic matter. (Staff must clean these manually.) Other hydroelectric sites would doubtless fair better. The nuclear plant would be about the toughest contender for a hydropower plant. On a full charge of fuel, it can run quite a while. These plants are very self-sustaining (at least on the primary side) once they are at power. The secondary side water problems would probably catch up and cause a shutdown if they weren't attended to (like the oil fired plants). The nuclear plant would be able to go for weeks to months. The winner in a contest would be a big photovoltaic plant where solar panels provide power by directly converting sunlight into electricity. Anyone who bets against them would probably not come out on top. With no moving parts, these guys should be able to run 'til the cows come home - and then some.
How long is 1000000 seconds in days or in hours?
1000000 seconds is approximately 11.57 days or approximately 277.78 hours.
What is role of physics in agriculture.Explain?
Now a days for doing agriculture all the farmers are depending up on electric motors for supplying water to the plants. So, with out water there is no chance for doing agriculture. . . Farmers are using the technologies in physics . Ex: for long days storage of seeds lasers are very helpfull to them.
What is a cool experiment?
you can use a magnifying glass to burn leaves outside on a really hot summer days (works better on dry leaves).
Why do plants need more leaves in summer?
Plants need more leaves in summer to capture as much sunlight as possible for photosynthesis, which is the process they use to convert sunlight into energy. With more leaves, plants can maximize their energy production during the longer days and stronger sunlight of the summer season. Additionally, leaves help plants regulate their internal temperature by providing shade and facilitating the exchange of gases necessary for photosynthesis.
How long does it take for leaves to appear after a seed germinates?
It generally takes a few days to a couple of weeks for the first leaves to appear after a seed germinates, depending on the plant species. Some plants may take longer to develop leaves while others may sprout leaves within a few days.
Why does wilting of leaves take place in hot summer?
the wilting of leaves take place in hot summer days because of excess transpiration.the process of transpiration take place in stomata which is present in leaves of plant.in order to excess transpiration plants wilt their leaves
Why are giraffes able to go a long period with out water?
Giraffes can go for about 7 days without water because they get moisture from the leaves.
Why do plants acquire more leaves during summer?
Plants acquire more leaves during summer to maximize photosynthesis and capture more sunlight for energy production. The longer days and increased sunlight provide optimal conditions for leaf growth, allowing plants to photosynthesize efficiently and support their growth and reproduction. This abundance of leaves helps plants store more energy and nutrients for future use.
Why do the leaves of a plant turn many colors in the fall?
As our days get shorter, plants cannot produce enough chlorophyll (through photosynthesis) to maintain their green color.
In how many days that gumamela leaves turn to yellow?
The gumamela leaves usually turn to yellow during the winter period. This is because during the winter the sun is usually absent which leads to the plants failing to make their own food.
Is Three Days Grace cool?
It is a matter of one's own opinion whether Three Days Grace is 'cool' or not.
How to apply sulphur to plants effectively?
To apply sulphur to plants effectively, mix powdered sulphur with water and spray it on the plants. Make sure to cover all parts of the plant, including the leaves and stems. Repeat the application every 7-10 days for best results.
How many leaves will a dicotyledon hahe after seven days?
The number of leaves a dicotyledon plant will have after seven days can vary depending on the specific plant species and its growth rate. On average, a dicotyledon plant may have a few primary leaves and possibly some secondary leaves after seven days of growth.
How can I make mint oil at home?
To make mint oil at home, crush fresh mint leaves and place them in a jar. Cover the leaves with a carrier oil like olive oil or coconut oil. Let the mixture sit for a few days, then strain out the leaves. Store the mint oil in a sealed container in a cool, dark place.
