Why should Asus be stores only in the glass containers please answer this ​

Do you mean acids?

Due to chemical reaction

Explanation:

Acids are only stored in glass containers because glass containers rarely react with any substance.They dont react with acids and prevent chemical reaction so the acids can be kept. If acids were kept in metal containers it would react .

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
