Answer
a) -40.°C & -40.°F
b) -269°C & -452°F
c) 25°C & 77°F
d) 3410°C & 6160°F
Work Step by Step
a) Celsius: 233K -273K= -40.°C
(remember because of sig figs there must be a decimal point after the zero bc it is significant out to the ones place)
Fahrenheit: (-40. x (9/5)) + 32
(-72) + 32= -40.°F
b) Celsius: 4K -273K= -269°C
Fahrenheit: (-269 x (9/5))+32
(-484.2)+32= 452.2°F
With sig figs: -452°F
(only significant out to the ones place)
c) Celsius: 298K -273K= 25°C
Fahrenheit: (25 x (9/5))+32
(45)+32= 77°F
d) Celsius: 3680K -273K= 3407°C
With sig figs: 3410°C (Only significant out to the tens place)
Fahrenheit: (3407 x (9/5))+32
(6132.6)+32= 6164.6°F
with sig figs: 6160°F
(*IMPORTANT* you should never take the significance of a problem twice so you should use 3407°C instead of 3410°C. You must remember at the end however the answer is only significant out to the tens place)
