State Henry's law. At the same temperature, CO_2 gas is more soluble in water then O_2 gas. Which one of them will have higher value of K_H ?

Between alcohol and amine having same number of C-atom, which one is more soluble in water & why?

A sphere ,a cubeand a thin circular plate,all made of the same meteriel and having the same mass are initially heated to a temperature of 200°C .Which of them will cool fastest and which one slowest when left in air at room temperature?

Perform the following activity and learn for yourself. Take two cloth pieces of the same size, roughly half a metre aquare each. One of these should be from natural fibre.the other could be a synthetic fibre. You can take help of your parents in selecting these pieces. Soak the pieces in different mugs each containing the same amount of water. Take the pieces out of the containers after five minutes and spread them in the sun for a few minutes. Compare the volume of the water remaining in each container. Do synthetic fabrics soak less/more water than the natural fabrics? Do they take less/more time to dry? What does this activity tell you about the characteristics of the synthetic fabrics? Find out from your parents about the durability, cost and maintenance of these fabrics, compared to the natural fabrics.

Why is ice at 273 K more effective in cooling than water at the same temperature?

H_2S , a toxic gas with rotten egg like smell, is used for the qualitative analysis. If the solubility of H_2S in water at STP is 0.195 m, calculate Henry's law constant.
