Show the calculation of the energy involved in condensation of 150 grams of steam at 100oc if the heat of vaporization for water is 2.26 kj/g.

Answer : The energy involved in condensation is, 339 kJ

Explanation :

Formula used :

where,

q = heat required = ?

L = latent heat of vaporization of water =

m = mass of water = 150 g

Now put all the given values in the above formula, we get:

Therefore, the energy involved in condensation is, 339 kJ

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
