A. Heat flowed from the soda to the ice cube and caused it to partially melt.

B. Coldness flowed from the ice cube to the soda, making the soda cooler.

C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda

D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.

Answer:

Option A

Step-by-step explanation:

According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.

(PLEASE HELP ASAP!!). One's intelligence quotient, or IQ, varies directly as a person's mental age and inversely as that person'
shusha [124]

Answer:40

Step-by-step explanation:This is a variation question

From the statement. Let the mental age be M and the chronological  age be C, then

IQ ∝M ∝1/C

⇒ IQ ∝ M/C

Introducing the proportionality constant

IQ = KM/ C

Given : M = 15, C = 30 , 1Q = 20

Substitute the given values into the equation

i.e 120 = K x 15/ 30

    120 = k/2

therefore k = 240

substitute k = 240 into the equation, we have

IQ = 240M/C

To find C when IQ is 120 and M is 20, we will substitute into the generated formula

i.e 120 = 240 x 20 / c

     120c = 480

            C = 480/120

             C = 40

Therefore , the chronological age of a person with mental age of 20 and IQ of 120 is 40
