Eva pumps up her bicycle tire until it has a gauge pressure of 413 kilopascals. if the surrounding air is at standard pressure, what is the absolute pressure in the bicycle tire? a. 33.9 kpa b. 49.7 kpa c. 312 kpa d. 514 kpa

D) The absolute pressure in the bicycle tire = 514 kPa

Explanation:

Given:

Gauge pressure (Pgauge)= 413 KPa

Standard pressure = Atmospheric pressure (Patm) = 101.3 kPa

To determine:

The absolute pressure in the bicycle tire (Pabs)

Formula:

Pabs = Pgauge + Patm

Pabs = 413 + 101.3 = 514.3 kPa

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
