A chemist observes that a large molecule reacts as if it were much smaller. The chemist proposes that the molecule is folded in

a way that causes it to react differently than expected and develops a series of experiments to test that proposition. How would the chemist's proposition be classified?

Answer:

Hypothesis

Explanation:

The following steps are applicable when we wish to prove a specific fact:

  • a hypothesis is made; this is a statement that we provide after some observations and we wish to either prove or deny it;
  • multiple experiments are carried out in order to gather significantly substantial amount of data that can be then further analyzed and any tendencies can be noticed;
  • based on the data gathered, conclusions are made: we either prove or deny the hypothesis. If hypothesis is proved, it may become a theory over long time.

In the context of this problem, we're at the first step where we make a hypothesis.

Method A is Convection

Method B is Conduction

Explanation:

From the problem, we can infer that method A is convection and method B is conduction.

Conduction, convection and radiation are the three main methods of heat transfer.

  • Conduction and convection requires material medium to propagate.
  • Radiation occurs in the absence of a material medium.
  • Conduction mostly occurs in solid. Here, heat is transferred from one hot end to the cold end of the solid. The vibration of the particles in the hot end causes the transfer of kinetic energy to the cold end until thermal equilibrium is reached.
  • In convection, heat is primarily transferred in fluids as a result of density differences. Convection involves the motion of the materials of the medium. Hot air is light and it rises whereas cold air is dense and it sinks.

Which one cools down faster, warm dry air or warm humid air ? (100 points) please explain
nadezda [96]

Answer:

Dry desert air cools much more quickly resulting in much colder nighttime temperatures.

Explanation:

The higher the moisture content in the air the harder it is to cool. Water has a much greater specific heat than dry air, retaining much more energy for each degree of temperature.

What is the density of a solid that has a mass of 100g and a volume of 25mL.?
Arte-miy333 [17]

Answer:

D = 4 g/mL

General Formulas and Concepts:

Density = Mass over Volume

  • D = m/V

Explanation:

<u>Step 1: Define</u>

m = 100 g

V = 25 mL

D = unknown

<u>Step 2: Find D</u>

  1. Substitute:               D = 100 g/25 mL
  2. Evaluate:                  D = 4 g/mL
