Hellllllllllllllllp plz...

Question 1 = 22 - 13 which is equal to 9.  ( question 1 is the one with the letter a in it.)

Question 2 = 40 + 3 which equals 43. ( question 2 is the one with the letter t in it.)

Question 3 = 15 - 11 which equals 4. ( question 3 is the one with the letter d in it.)

Question 4 = 32 - 19 which equals 13. ( question 4 is the one with the letter s in it.)

Hope this helps!

A. Sumar 13 y 9.

22=22

B.Mover todos los términos que no contengan

d al lado derecho de la ecuación.

d=4

C.Reste 3 de −40

t−43

D.Reste 19 de 5

32=−14

Yes

Step-by-step explanation:

Water molecules are always moving, some molecules are hit by other molecules which cause them to gain speed. These molecules hitting each other cause the energy and the temperature to raise. Temperature is the average kinetic energy of the molecules. Slower moving molecules have a lower temperature(colder) while faster moving molecules have a higher temperature (hotter). The increasing temperature causes the water molecule bonds to break, which causes water molecules to turn into gas. The breaking of bonds of molecules is evaporation, it involves a change of state, from liquid to gas. The higher the temperature, the higher the rate of evaporation. When the temperature of water increases the water molecules gain more energy. When the water molecules’ temperature rises the water molecules start to move faster and thus evaporate faster. Basically the higher the temperature the higher the rate of evaporation (Factors Affecting the Rate of Evaporation). This is the most notable factor that affects rates of evaporation. The way we will test this is by having two bowls of water. One bowl will be exposed to normal conditions, while the other bowl will be exposed to a heat lamp. After twenty-four hours we will compare the mass of both bowls, and see if they change. After this we will conclude based on the data we received.
