Answer:

hydrant flying with balloon, balloon has lithp letting air out, bee: really yum balloon

    =                           =                                 =                                   =

hydrogen              helium                     lithium                     beryllium

be bore on the balloon, balloon pops, hydrant drops and makes a car bomb

           =                                                                                                  =

    boron                                                                                              carbon

night row general gets hurt by car bomb nearby, that general gets off boat

        =                                

nitrogen

wearing oxygen mask, mask is full of fluride gel, then he got neon teeth

             =                                               =                                      =

         oxygen                                fluorine                                neon

(try making a story out of the elements, use your imagenation)

HELP!!!!! IM TIMED
Marianna [84]

Answer:

Substance X has the highest temperature because its particles have more kinetic energy.

Explanation:

The temperature of a substance is an indicator of the average kinetic energy of the molecules of the substance.

In particular, the two quantities are directly proportional to each other, as shown in the equation:

KE=\frac{3}{2}kT

where

KE is the average kinetic energy of the molecules

k is the Boltzmann's constant

T is the temperature of the substance

In this problem, we have a figure showing the movement of particles for 2 substances.

For substance X, the particles have long movement lines behind them: this means that they move faster, so their average kinetic energy is larger, and so the temperature of substance X is higher.

For substance Y, the particles have short movement lines behind them: this means that they move slower, so their average kinetic energy is smaller, and so the temperature of substance Y is lower.

Therefore, the correct option is

Substance X has the highest temperature because its particles have more kinetic energy.
