Why does a group of warmer atoms take up more volume than a group of cooler atoms?

Answers

Warmer atoms expand. There is also more movement. This is also explained when putting it into terms with solid vs. gas. In a solid, the atoms vibrate, but they can't move very far because there is not a lot of space between them. In a gas, on the other hand, the atoms are spread apart, and they move very fast. Putting it into context with water, the steam (gas) version is hot, and the ice cube (solid) version is cold. Which one moves more freely? The gas.

A 1,500-kg car is moving at a speed of 10 m/s. What is the car's kinetic energy?

Answers

Kinetic Energy of particle of mass, m moving with velocity, v is

K.E. = ½mv²

m= 1500 kg

v = 10 m/s

((1/2)*1500)* $10^(2)$

750*10=75000

KE=75 joules

How can you figure out kinetic energy?

According to classical physics, kinetic energy (KE) is determined by multiplying an object's mass by its velocity squared, or half of the mass (1/2*m). The kinetic energy of an object with a mass of 10 kilograms (m = 10 kg) travelling at a speed of 5 m/s (v = 5 m/s) is equal to 125 joules, or (1/2 * 10 kg) * 5 m/s2.

a vehicle with a mass of 1200 kg and a speed of 20 m/s. KE = ½mv 2

KE = ½ x 1200 x (400) = 240,000 J 2.

Hello!

If The 1500 kg car will increase its velocity to 10 m/s. What Will be its kinetic energy ?

We have the following data:

m (mass) = 1500 kg

v (velocity) = 10 m/s

KE (kinetic Energy) = ? (in Joule)

Formula to calculate kinetic energy:

$\boxed{KE = (1)/(2) *m*v^2}$

Solving:

$KE = (1)/(2) *m*v^2$

$KE = (1)/(2) *1500*10^2$

$KE = (1)/(2) *1500*100$

$KE = (150000)/(2)$

$\boxed{\boxed{KE = 75000\:Joule}}\:or\:\boxed{\boxed{KE = 75\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}$

A particular atom becomes more energetically stable when it loses a single electron. It is most likely an atom of which of the following elements?magnesium (Mg)
cesium (Cs)
fluorine (F)
boron (B)

Answers

Answer: Cesium (Cs)

Explanation:

Elements lose or gain electrons in their valence shell so as to maintain stability by either forming duplets or octet configuration. I.e 2 electrons in its outer shell to form duplet or 8 in its outer shell to form octet configurations. All metals with exception of Metalloids lose electrons in its outer shell corresponding to its group number to form stability. I.e group 1 elements lose 1 electrons to form stability, group two elements lose 2 electrons, group 3 and so on. From the elements listed above, Cesium is a group 1 element and it will require to lose 1 electron so as to form stability. Magnesium (Mg) loses 2 electrons to form stability, Fluorine (F) a non metal from group (vii) requires 1 electron to be stable and boron a group (v) element would need 3 electrons to form stability.

The answer is Cesium (Cs)

Answers

Because oil or petrol is less dense than water therefore, instead of being absorbed by the water, it separates leaving the petrol on top of the water instead of in it or underneath it
