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
The specific heat capacity of alcohol is approximately 2.44 J/g°C. To calculate the calories required, you can use the formula: Calories = mass (g) x specific heat capacity x temperature change (°C). Plug in the values: Calories = 13 g x 2.44 J/g°C x 12°C = 377.76 calories.
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.
Saying something boils at 65 degrees means that that is the minimum temperature required to vaporize it. So anything under 65 degrees and it will return to a liquid. So about 64 degrees or so.
Administering an alcohol rub or sponged bath is practiced to help reduce a fever due to the cooling effect of the alcohol as it evaporates from the skin. This process helps to increase heat loss from the body, which can help in bringing down the elevated body temperature during a fever.
The heat of vaporization of alcohol, such as ethanol, is approximately 38.56 kJ/mol at its boiling point. This is the amount of energy required to convert a liquid into vapor at a constant temperature.
The normal temperature of alcohol, specifically ethanol, is 78.37°F (25.76°C).
23-11 = 12 13 * 12 = 156
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 ------------------
It takes 2.44 calories of heat to raise the temperature of one gram of ethyl alcohol by 1 degree Celsius.
Of course.
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.
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.
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.
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.
Yes. Alcoholic beverages contains a lot of calories, so drinking those can certainly make you put on weight.
Alcohol causes core body temperature to decrease. However, flushing caused by alcohol may make someone think they are getting warmer rather than colder.
