express in the standard form of linear equation in two variables x = 10 +7y /3​

Answer 1

Answer:

After all the sulphur has burnt, remove the combustion spoon from the jar and put some water in the gas jar, cover it with a lid and shake it to dissolve sulphur dioxide gas. We will divide this solution in two parts and test it with blue litmus paper and red litmus paper

Answer 2

Answer:

Given that

Let us assume that the lowered temperature as negative,

Initial temperature = 40oC

Change in temperature per hour = -5oC

Change in temperature after 10 hours = (-5) × 10 = -50oC

∴The final room temperature after 10 hours of freezing process = 40oC + (-50oC)

= -10oC

The room temperature 10 hours after the process begins= -10oC
