HELP ASAP ANSWER ALL OF THIS FOR 55 POINTS+BRAINLIST 1. Heat is transferred directly from one particle of matter to another by the process of

2. A circular flow of warmer fluid and cooler fluid is called a(n)

3. Heat is always transferred from to

4. is the transfer of energy by electromagnetic waves.

5. Heat that is transferred by the movement of currents within a fluid is called

6. The only form of heat transfer that does not require matter is

7. Water bubbles up through a hot spring at Yellowstone National Park. What method of heat transfer is this?

A conduction B convection

C radiation

D specific heat

In each of the following examples, identify whether heat is being transferred through conduction, convection or radiation. Some may have two possible answers. Choose the answer that best fits the situation.

1 = a

2= b

3 = c,d

4 = c

5 = a

6 = d

7 = a

Explanation:

I hope that this helps, I kinda rushed on it

1. conduction

2. a convection current

3. Heat is always transferred from the object at the higher temperature to the object with the lower temperature

4. n!Heat is always transferred from the object at the higher temperature to the object with the lower temperature

5.convection

6. Thermal radiation

7. convection again!

A. Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.

B. Radiation is the transfer of thermal energy through thermal emission.

C. the heat required to raise the temperature of the unit mass of a given substance by a given amount

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
