2.460 is the specific heat of ethyl alcohol in J/gC, so I will find joules and then convert to calories.
q(joules) = mass*specific heat*change in temp.
q = (13 g alcohol )(2.460 J/gC)(23 C - 11 C)
= 383.76 joules (1 calorie/4.184 joules)
= 92 calories
------------------
There are 4 calories for every gram of carbohydrates. There is also 4 calories per gram of protein and 9 calories per gram of fat. Finally there are 7 calories per gram of alcohol.
There are 3 litres of alcohol in your starting mixture of 4 litres. If you add 6 litres of water you will have 3 litres of alcohol in a total of 10 litres. This is the required strength.
Let a be the number of ounces of 25% alcohol required. Then, 25a + (30x9) = 28(9 + a) 25a + 270 = 252 + 28a 3a = 18 a = 6 Then 6 ounces of 25% alcohol + 9 ounces of 30% alcohol produces 15 ounces of 28% alcohol.
A laboratory thermometer is a device for measuring temperature ranges. It can take the form of a manual (mercury or alcohol) or electronic (digtal).
A solution of 30 percent alcohol (ethanol) has a freezing point of approximately -10 degrees Celsius (14 degrees Fahrenheit). The exact freezing point can vary slightly depending on the specific mixture and impurities present, but it generally falls within this range.
23-11 = 12 13 * 12 = 156
It takes 2.46 calories of heat to raise the temperature of one gram of ethyl alcohol. Calories are the energy available from the metabolism of a food.
Of course.
If the Specific heat of alcohol is .58cal/g C, then SP = Heat /(g * Change in Temperature) SP = .58 cal / g * C g = 13 g change in Temp = 23 C - 11 C = 12 C .58cal/g C = Heat / 13 g * 12 C .58* 13 * 12 = heat Heat = 90 cal
You gain weight when you consume more calories than your body burns. Alcohol has a lot of calories. If you don't increase the amount of exercise you get to balance the increase in calories you will gain weight from drinking.
Who said alcohol doesn't have any calories? 1 gram of alcohol has 7 calories.
Yes, the alcohol percentage of a liquid can change with temperature because temperature affects the volume of the liquid. As temperature increases, the volume expands, leading to a decrease in alcohol concentration in the liquid. Conversely, as temperature decreases, the volume contracts, causing an increase in alcohol concentration.
The body uses calories to provide energy to the body. Some calories have nutritional value and others don't and are referred to as empty calories. The calories present in alcohol are empty calories and contain 7 calories per gram.
When the temperature goes up, the mercury or alcohol inside the thermometer expands, causing the level to rise. This increase in volume is directly correlated with the increase in temperature, allowing the thermometer to indicate the higher temperature.
When isopropyl alcohol is mixed with water, it releases energy due to the solvation process, leading to an overall increase in temperature. This is because energy is released when the intermolecular forces between water molecules and isopropyl alcohol molecules are formed.
Yes. Alcoholic beverages contains a lot of calories, so drinking those can certainly make you put on weight.
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
