How much heat is absorbed by a 112.5 g sample of water when it is heated from 12.5 °C to 92.1 °C? (Specific heat capacity of wat
Alborosie

Answer:

\boxed {\boxed {\sf37,467.72 \ Joules }}

Explanation:

We are asked to find how much heat a sample of water absorbed. Since we are given the mass, temperature, and specific heat, we will use the following formula.

q=mc \Delta T

The mass (m) of the sample is 112.5 grams. The specific heat capacity of water (c) is 4.184 Joules per gram degree Celsius. The difference in temperature (ΔT) is found by subtracting the initial temperature from the final temperature.

  • ΔT= final temperature - initial temperature

The water was heated from 12.5 degrees Celsius to 92.1 degrees Celsius.

  • ΔT= 92.1 °C - 12.5 °C= 79.6°C

Now we know three variables and can substitute them into the formula,

  • m= 112.5 g
  • c= 4.184 J/g °C
  • ΔT= 79.6 °C

q= (112.5 \ g )(4.184 \ J/g \textdegree C)(79.6 \textdegree C)

Multiply the first 2 numbers. Note the units of grams cancel.

q= (112.5 \ g *4.184 \ J/g \textdegree C)(79.6 \textdegree C)

q= (112.5  *4.184 \ J/ \textdegree C)(79.6 \textdegree C)

q= (470.7 \ J/ \textdegree C)(79.6 \textdegree C)

Multiply again. This time the units of degrees Celsius cancel.

q= (470.7 \ J/ \textdegree C *79.6 \textdegree C)

q= (470.7 \ J *79.6 )

q= 37467.72 \ J

37, 467.72 Joules of heat are absorbed by the sample fo water.

Compounds in alcoholic beverages that enhance flavor and appearance but may contribute to hangover symptoms are called:_____.
olga_2 [115]

Compounds in alcoholic beverages that enhance flavor and appearance but may contribute to hangover symptoms are called congeners.

<h3>Alcoholic beverages:</h3>

Congeners are compounds that add to the flavor, smell, and appearance of most alcoholic beverages. These substances may make hangover symptoms worse. Because they contain fewer congeners than whiskey, brandy, and red wine, clear alcoholic beverages like gin and vodka have less of a hangover-inducing effect.

The impact of ethanol, or the alcohol in your drinks, is the primary contributor to a hangover. It is a poisonous substance that acts as a diuretic in the body, which causes you to urinate more frequently and increases the likelihood that you will become dehydrated. The incidence and intensity of hangovers are both increased by congeners, substances created during the digestion and maturation of alcohol.
