Ionization enthalpy is the amount of energy required to separate the most loosely bound electron of an isolated gaseous atom from its valence shell. Ionization enthalpy increases as we move down the group. Same is the case with alkali metals but lithium has anomalous properties due to which its ionization enthaly is the most among the alkali metals.

It is the amount of energy that can be converted into useful work is called Gibbs free energy

Himanshu Tiwari 7 years, 10 months ago

Hey Gibbs free energy is one of the important or boring topic and Gibbs free energy mainly have a simple definition or if you say that if not definition it's the formula that is - 2.303 multiply Dell nTR multiply log k c

Has been increased temperature the thickness also decreases and the viscosity as well decreases

Anjali Kumari 7 years, 10 months ago

Bcoz temp Inc. hoga toh molecules dhurr hoge (move apart ) kyuki unka intermolecular forces Dec ho jayega aur viscosity Dec. hogi

Rahul Singh Singh 7 years, 10 months ago

Because viscosity is directly proportional to temperature

Greenhouse effect is mainly the effect that is caused by the UV radiations from the sun and when they come on the earth day mainly causes Cancer and heat of the environment and gases like carbon dioxide heat environment and causes global warming this is called greenhouse effect

Anmol Sharma 7 years, 10 months ago

When Sun's radiations reach the Earth, some of them are absorbed and much are reflected back in form of infra-red radiations, which are trapped by Earth's atmosphere.This cause warming effect on the Earth and this effect is called greenhouse effect .
