Why are the marked lines on a beaker like this useful for measuring the volume of a liquid? A liquid maintains its shape in the

beaker, so the beaker can measure the liquid’s height, and the height cubed equals the liquid’s volume. A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume. A liquid is usually made of neutral atoms, and the beaker does not add or remove energy from the atoms, thereby preventing ionization. A liquid is compressible, but since the beaker does not have a top on it, the liquid will maintain its same volume THE ANSWER IS (B)

Answer : Option B) <span>A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume.

Explanation : When a liquid is poured into a beaker the liquid takes the internal shape of the beaker which is circular in shape, according to the markings on the beaker one can measure approx quantity of fluid required and perform the experiment. The area of circular of the beaker when multiplied with height of liquid gives the total volumes of fluid present in it.

A van moves with a constant speed
Kitty [74]

Answer:

1.5 hours or 90 minutes

Explanation:

Velocity = d/t

V = 64 mi / hour or 96 mi / 9 min OR 16 mi / 15 min

D = 96 miles

Velocity * Time = Distance

Time = Distance / Velocity

T = 96 mi / 64 mi / hour

96 / 64 = 1.5 mi per hour

T = 1.5 hours or 90 minutes

1) Why are the antimony and beryllium ions so small? Differentiate between the causes.
Viefleur [7K]
1. For this question, the adjective small must be percepted in a relative sense. This is because it is not the smallest ion (that would be hydrogen). It could be that the antimony and beryllium ions are smaller compared to their neutral forms. This is because they donate electrons when ionized. As a result, the electrons are reduced, so does the electron cloud which makes the radius much smaller.

2. The periodic table is arranged in terms of increasing atomic number. For neutral atoms, the number of protons (atomic number) is equal to the number of electrons. So, the farther we go down the table, the higher the atomic number. The higher the atomic number, the bigger the electron cloud which makes the atomic radius bigger. Because by definition, atomic radius is the length from the nucleus to the farthest electron from the nucleus.

Given 16.2 grams of substance Y, if the substance absorbs 2722 joules of energy and the specific heat of the substance is 9.22 J
snow_tiger [21]
Since the substance absorbs heat, it is expected that the temperature will rise. The formula for the internal energy of a substance is given by the equation:

ΔU = mCpΔT

where:

ΔU = internal energy
m = mass of substance
Cp = specific heat capacity of substance
ΔT = change in temperature

ΔU = 2722 Joules = 16.2 grams (9.22 J/g-°C) (Tf - 26°C)

This gives a final temperature of Tf = 44.22 °C
