3.According to paragraph 2, what is one reason for thinking that at one time, there were significant amounts of water on Venus? A. Because of Venus’ size and mass, its volcanoes probably produced much more water vapor than volcanoes on Earth did. B. The low temperature of Venus' earl...
Since water vapor is a greenhouse gas, this humid atmosphere—perhaps denser than Earth’s present-day atmosphere, but far less dense than the atmosphere that envelops Venus today—would have efficiently trapped heat from the Sun. At first, this would have had little effect on the oceans of ...
than Earth is, enough of the liquid water on Venus would have vaporized to create a thick cover of water vapor clouds.Since water vapor is a greenhouse gas, this humid atmosphere—perhaps denser than Earth’s present-day atmosphere, but far less dense than the atmosphere that envelops Venus...
The density reading is taken by looking at the scale, where the level of the sample liquid aligns with a marking on the hydrometer scale. Most hydrometers measure the specific gravity of samples: in simple terms, a hydrometer tells the user if a liquid is denser or less dense th...
Some of the pistils are starting to turn color on the following buds, but there are still too many white pistils. These buds have at least a few weeks to go before they’ll reach their highest levels of THC. The good news is your buds will get bigger and denser in that time! Not...

“The forest is like our very life for us forest guardians. The last thing we want is to see the forest shrink.” This is a line passed down for four generations in the Zhu family. At present, the green hues of ...

Usually solids are denser than liquid, so why is it different for water? Is ice a gas, a solid or a liquid? When water freezes and becomes solid ice, the hydrogen bonds create a crystal structure and there is fixed space between e...
Which molecule has a higher vapor pressure at a certain temperature: CH4 or PbH4? Explain. How many water molecules are there in 35.7 L of water vapor at STP? Which among the following is true? i. When vapor pressure of the liquid increases its boiling point decreases. ii...
