Adding a spoonful of dry baking powder is added to a glass of cold water and identical quantity is added to a glass of hot water which of the following results would occur
When baking powder is added to water, it reacts with the water to produce carbon dioxide gas, which causes the mixture to bubble and fizz. This is due to the release of carbon dioxide gas when the acid (found in baking powder) reacts with the water.
If a spoonful of dry baking powder is added to a glass of cold water, the reaction will be slower because the cold water will slow down the reaction between the baking powder and the water. The carbon dioxide gas will still be produced, but the bubbling and fizzing may be slower and less vigorous.
On the other hand, if a spoonful of dry baking powder is added to a glass of hot water, the reaction will be faster because the hot water will speed up the reaction between the baking powder and the water. The carbon dioxide gas will be produced more quickly, resulting in more vigorous bubbling and fizzing.
Therefore, the glass of hot water will have a more pronounced reaction with the baking powder, producing more bubbles and a stronger fizzing sound compared to the glass of cold water.
