Where did water become gas?

ASHA 777 [7]

Answer: Water becomes gas at D-E.

Explanation:
In the flat line D-E water is absorbing energy to become gas, and when the water is completely gas, the temperature will increase again therefore the line will rise up.

What did Thomas Young, Max planck and Albert Einstein contribute towards the nature of light?

Lera25 [3.4K]

The contribution to the nature of light-

Thomas Young - wave nature of light (double-slit experiment)

Max Planck - E = hv

Albert Einstein - a quantum theory of light

Thomas Young proposed the most important double-slit experiment which shows that light acts like a wave and shows the pattern of interferences.

Max Planck proposed that light is proportional to frequency. He gave the equation, E = hv, where E is the energy of light, h is Planck's constant, and v is the frequency.

Albert Einstein proposed the quantum theory of light. He determined that light exists in discrete quanta of energy called photons.

Select the pair that consists of a base and its conjugate acid in that order. CO32−/CO22−

lana [24]

Answer: The pair that consists of a base and its conjugate acid in that order. $NH_3/NH_4^+$

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

$H_3PO_4\rightarrow H_PO_4{2^-}+2H^+$

$H_2CO_3\rightarrow HCO_3^-+H^+$

$NH_3+H^+\rightarrow NH_4^+$

$HCO_3^-\rightarrow CO_3^{2-}+H^+$

$NH_3$ is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms $NH_4^+$ which is a conjugate acid.
