Test #1

#1 We know so much about electrons because of j.j Thompson in 1897.

#2 test

         #1 What ions do acids have?
         #2 Who's model of the atom was called the peach pit model?
         #3 How are acids discibed? ( hint how they feel smell..)
         #4 Whats the differnce detween thermal energy and specific heat?
         #5 Balence the equation NO+Cl= 3OC+ OClC

#1 Kelvin, fahrenheit,celsius.

#2 Thermal energy is related to heat because heat is the way thermal energy is transferred from matter to matter.

#3 When something has a high specific heat then it can absorb a great deal of thermal energy.

#4 An ice cube melts in your hand because the heat from your hand is making the ice melt.

#5 This depends on the objects chemical makeup.

#6 It works like  speedometer for particles

#7 The three measurements are the same because they each have a freezing point and a boiling point. But they are also different because the way they are used. Kelvin is used in space and Fahrenheit is used in measureing temp in the US. Celsius is used in most of Europe.

#8 -12.78

#9 842.22
#10 209,000

#11 radeation conduction convection

#12 Up

#13 A conductor is usual cool to the touch and an insulators aren't.

#14 I think it would be a better conductent because you use cooper in wiring so it would work as a pipe.

#15 I would do both but use a clear tent so that the heat of the fire would come through the tent and warm the inside of in and this is radiation.

#16 The temp. at which it is at for water its freezing temp. is 32 and boiling is 212 so at 32 it will turn into a solid and at 212 it will begin to become a gas.

#17 When a substance's termal energy increases then the object cold last longer and if its edible it will taste better. Ex farmers in Florida will spray water on their oranges before a frost and when the water freezes, when the change of state from water to ice occurs that energy is transferred to the orange so it keeps it ripe.

#18 the temp. at which it melts.

#19 A solid melts because of extreme temps.

#20 You poke a hole in a potato because if you don't then the water thats in the potato will become steam and then the potato will blow up.

#21 Thermal energy is related to steam engines because when the heat of the fire will heat the water till the water becomes steam and this is how it works.

#22

#23 Because there safer then engines that are out side

#1 Terms Acid - a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue limos paper.
#2  Neutralizing - the loss of a distinctive feature of one of a pair of phonemes that are other wise differed and limited.
#3 indicator - a pointing or directing devices a pointer on the dial of an instrument to show speed, and temperature.
#4 Corrosive- Harmful or destructive; deleterious.
#5 Hydroxide ion- the anion OH having one O and one H atom.

#6 It is measured by how much substance there is.

#7 Because of its characteristics property of matter.

#8 Temp. and pressure.

#9 The temp. can effect what state of matter it is in either in a solid or a liquid.

#10 By when the object melts and what the temp is when it becomes a solid again.

#11 The four properties of an acid are it conducts electricity, sour tasting, reacts with a base to neutralize its properties, and reacts with  active metals to liberate hydrogen gas.

#12 Conducts electricity, bitter tasting, reacts with an acid to neutralize its properties, feels slippery on the skin.

#13 If the paper turns red the it is an acid if it turns blue than its a base.

#14 If the food has a bitter taste to it then it might have a week acid.

#15 You were gloves because you might get dirty.

#16 Acids have H ions

#17 Hydrogin ion positively charged

#18 It would become salt water

#19 So your hands don't get dirty
