Ex. 4 When drinking an ice-cold beverage, a person must raise the temperature of the beverage to 37.0°C (normal body temperature). One argument for losing weight is to drink ice-cold beverages since the body must expend about 1 calorie per gram of water per degree Celsius—i.e. the specific heat of water = 1.00 cal/g·°C —to consume the drink.

Calculate the amount of energy expended (in cal) to consume a 12-oz beer (about 355 mL) if the beer is originally at 4.0°C. Assume the drink is mostly water and its density is 1.01 g/mL. I GOT THIS PART.

NEED HELP WITH PART B....

part b? If the label indicates 103 Calories(where 1 nutritional Calorie (Cal) equal 1kcal), what is the net calorie gain or loss when a person consumes this beer? Is this a viable weight loss plan?

An ice-cream producer’s sales are affected by the maximum daily temperature (typically, more sales when it is hotter). In summer the maximum daily temperature (in degrees Celsius) has a normal distribution with a mean of 31 and a variance of 25. The probability that the average maximum daily temperature on 18 randomly selected summer days is higher than 29 degrees is (to two decimal places)
