The white tern is a seabird that catches fish by plunging into the water. What physical features of the bird likely make this fe
V125BC [204]

White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.  

The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.

What is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K), is heated from 25°C to 15°C
Gemiola [76]

Answer:

A. 21 J

Explanation:

Your temperature change is 10 degrees Celsius, or 10 Kelvin, it makes no difference either way.

Cp = 2.06 J/g•K

Multiply by the temperature change to just get J/g

2.06 J/g•K • 10 K = 20.6 J/g ≈ 21 J/g

How can a substance boil when it is cold?
igomit [66]
When the ambient pressure is reduced to below the vapor pressure of the liquid, the liquid boils. Water typically boils at 100°C when the pressure is equal to 1 atm, but when the pressure is reduced using a vacuum pump, the water boils at room temperature.
