Convert the following temperatures to degrees Celsius or Fahrenheit: (a) 95°F, the temperature on a hot summer day; (b) 12°F,
Elis [28]

Answer:

a) 35°C, the temperature on a hot summer day

b) -11.11°C, the temperature on a cold winter day

c)  a 38.88°C fever

d) a furnace operating at 1011.11°C

e) 523.67°F ( theoretically the lowest attainable temperature )

Explanation:

  • °C = ( °F - 32 ) / 1.8
  • °F = ( 1.8 * °C ) +32

a) 95°F ⇒ °C = ( 95 - 32 ) / 1.8 = 35°C

b) 12°F ⇒ °C = ( 12 - 32 ) / 1.8 = -11.11°C

c) 102°F ⇒ °C = ( 102 -32 ) / 1.8 = 38.88°C

d) 1852°F ⇒ °C = ( 1852 -32 ) / 1.8 = 1011.11°C

e) 273.15°C ⇒ °F = ( 1.8 * 273.15 ) + 32 = 523.67°F
