Aresearcher wishes to estimate the average blood alcohol concentration (bac) for drivers involved in fatal accidents who are found to have positive

Ounces of beverage consumed: 1 beer = 12 oz.

Glass of wine = 5 oz. / 1 shot = 1.5 oz.

Your Weight (lbs)Percentage of alcohol in beverage:

1 beer = 4-7% / Glass of wine = 11-13% / 1 shot = 40%

Hours spent drinking

Explanation: The BAC is gotten by calculating, various parameters such as:

1. The ounces of beverage or glass wine consumed.

2. Your weight multiply by the percentage of alcohol in the beverage.

3. The number of hours used in drinking.

4. Then the percentage would be produced.

This would show the average blood alcohol concentration in the drivers blood.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
