What are the chemical properties of benzene? Benzene has a boiling point of 80.1 °C (176.2 °F) and a melting point of 5.5 °C (41.9 °F), and it is freely soluble in organic solvents, but only slightly soluble in water. What are the physical properties of phenol? Phenols are similar to alcohols but form stronger […]
Which F stop is sharpest?
Which F stop is sharpest? The sharpest aperture of your lens, known as the sweet spot, is located two to three f/stops from the widest aperture. Therefore, the sharpest aperture on my 16-35mm f/4 is between f/8 and f/11. A faster lens, such as the 14-24mm f/2.8, has a sweet spot between f/5.6 and f/8. […]
What is the role of stomata in gas exchange?
What is the role of stomata in gas exchange? Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf. What are stomata mention their importance? Stomata serve a […]
Can change in potential energy be negative?
Can change in potential energy be negative? potential energy is scalar quantity and a change in scalar can be either positive or negative but force is a vector and the negative rate of change of potential provides you force -its magnitude as well as its direction. gravitational potential energy is taken to be zero at […]
What is rate of change of displacement called?
What is rate of change of displacement called? Velocity is defined as rate of change of displacement. What do you mean by negative displacement? Displacement is quantity which considers magnitude as well as direction. If you move in forward direction with reference to your reference point ( initial position) then the displacement will be positive […]

Where do greenhouse gases absorb radiation from?
Where do greenhouse gases absorb radiation from? Water vapor, carbon dioxide, methane, and other trace gases in Earth’s atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth’s surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth. Why is the natural greenhouse effect of […]
