Volume of tea V = 2.0L = 2000 mL density d = 1.01 g/ mL mass of tea m = V * d = 2000mL * 1.01g/mL = 2020 gWhen we assume that the tea was initially at 72, the final temperature of the tea in F is 91.
The answer in this question is B. 91
You pick a system for which no control sample exists, so that no one can show that the alleged causal relationships you assert do not, in fact, lead to the phenomenon you claim to have observed.
Acceleration is the rate at which velocity changes.

Simply equate the two.
</span>
<span>dV / dt = F/m </span>
<span>F*dt = dV * m </span>

The impulse you give any object (average force * time elapsed) is equal to its change in momentum (mass * change in velocity).</span>
Answer:
0.240 J/g/°C
Explanation:
q = mCΔT
47.3 cal = (55.00 g) C (15.0°C)
C = 0.0573 cal/g/°C
Usually, specific heat is measured in J/g/°C, so we can convert:
C = 0.0573 cal/g/°C × 4.184 J/cal
C = 0.240 J/g/°C
Fractional distillation is the most efficient technique to separate solid benzoic acid mixed with a volatile alkyl halide liquid components.
<h3>Fractional distillation :</h3>
Separating a mixture into its constituent parts, or fractions, is known as fractional distillation. Chemical compounds are separated by heating chemical mixtures to a temperature at which one or more fractions of the mixture evaporate. Distillation is used to fractionate.
Boiling a mixture of liquids results in vapors rising up a glass tube known as a "fractionating column," which is followed by separation. The fractionating column, which is placed between the flask holding the mixture and the "Y" adaptor, improves the separation of the liquids being distilled.
<h3>Uses of fractional distillation :</h3>
Alcohol purification, desalination, crude oil refinement, and the creation of liquefied gases from air are all applications of distillation.
