Answer:
At very low temperatures, gases expand less for a given pressure change than they do at high temperatures
The question's incomplete unfortunately, which observations?
Answer:
$ 62.578
Explanation:
Conversion factors:
1 gal = 3.785 L
1.609km = 1 mi
$1.26 = 1 euro
1 week = 7 days
Converting the car’s mileage from mi/gal to km/L
39 mi/gal x 1 gal/3.785L x 1.609km/1 mi = 16.578 km/L
Finding the L required in a day
107 km x 1L/16.578 km = 6.45 L
Finding the euro spent in day
1.10 euro/L x 6.45 L = 7.095 euro/ day
Finding the euro spent in a week and converting it to dollars
7.095 euro/ day x 7 days x $1.26/ 1 euro = $ 62.578
3. Explain the meaning of each term in the symbol
(AZ)X
a. True
b. False
Answer:
True. A gas does not have a definite volume. Therefore, making this statement correct.
Explanation:
true
B. Bright areas appear on the screen
C. Light bends around the edges of the slit
D. Dark areas appear on the screen
The three phenomena occur during a double-slit experiment and support the wave model of light is bright areas appear on the screen, light bends around the edges of the slit, dark areas appear on the screen. Therefore, option B, C and D are correct.
The double-slit experiment, which was conducted to study the characteristics of light in the eighteenth century, has subsequently been found to illustrate the duality of photons as well as the ideas of superposition and quantum interference.
It implies that things we refer to as "particles," like electrons, in some ways mix the traits of both particles and waves. That is quantum physics' renowned wave-particle duality.
The three phenomena occur during a double-slit experiment and support the wave model of light is bright areas appear on the screen, light bends around the edges of the slit, dark areas appear on the screen.
Thus, option B, C and D are correct.

Answer:BC And D
Explanation:just did the quiz
A rate equation can be written based on the rate constant k, concentration of reactants and half life time t1/2 of reactant if given. [A⁰] is the initial concentration of reactant A and [A]t be the final concentration.
Rate of a reaction is the rate of decrease in concentration of reactants or rate of increase in concentration of products. Rate of the reaction written in terms of molar concentration of reactants is called the rate law.
Consider the simplest reaction A gives B. Here the only one reactant is A. The molar concentration of A is written as [A]. The rate constant k is then,
k = [B] / [A]
If any coefficients attached with them it is written as power of the concentration term. Now, the rate of the above reaction is written as follows:
rate r = k [A]
Sometimes the initial and final concentrations of A can be considered. Where, [A⁰] is the initial concentration and [A]t be the final concentration.
The half life t1/2 is the time taken to consume half of the reactants concentration.
