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.

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
