1. Convert 32°C into K
2. Convert 80°F into C
3. Convert 580°F into K

1. 305.15K

2. 26.67C

3. 577.59K

Explanation:

When converting Celsius to Kelvin, just add +273.15 to the given Celsius.

: C + 273.15

If Fahrenheit to Celsius, subtract 32 to the given Fahrenheit and divide it by 1.8

: (Fahrenheit - 32) / 1.8

If Fahrenheit to Kelvin, just do the same as you did in converting F to C but add 273.15

: (Fahrenheit - 32) /1.8 + 273.15     ...like this

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
