Answer:

3.2 Calories

Explanation:

Here we will use a formula

Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass

As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat is .16 calories/gm

Incorporating the values of mass (m), temperature(T) and specific heat (c) in formula.

calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C

= 3.2 calories

Hope it helps:)

NO3- will affect the pH of a solution. The ion will decrease the pH of a neutral solution. No3- ion is a conjugate base of a strong acid, therefore, if it added to a neutral solution of pH 7, it will change the pH of the solution by decreasing the pH, that is, the solution will become acidic in nature.
