Question

A weather forecast states that tomorrow's temperature will be twice what it is today. Today's temperature is 10°C. Using the forecast, compute tomorrow's temperature on the Celsius, Fahrenheit, and Kelvin scales. Which value is most believable?

1) 20°C, 68°F, 293.15K
2) 20°C, 36°F, 293.15K
3) 20°C, 50°F, 293.15K
4) 20°C, 68°F, 273.15K

Answer 1

Tomorrow's temperature will be 20°C, 50°F, 293.15K according to the weather forecast. The most believable value is option 3.

Step-by-step explanation:

According to the weather forecast, tomorrow's temperature will be twice what it is today. Today's temperature is 10°C. To calculate tomorrow's temperature, we multiply today's temperature by 2:

Tomorrow's temperature = 10°C x 2 = 20°C.

To convert this temperature to Fahrenheit, we can use the formula:

Fahrenheit = (9/5) x Celsius + 32.

Plugging in the value of Celsius temperature, we get:

Fahrenheit = (9/5) x 20 + 32 = 36°F.

To convert the temperature to Kelvin, we use the formula:

Kelvin = Celsius + 273.15.

So, the temperature in Kelvin is:

Kelvin = 20 + 273.15 = 293.15K.

Therefore, the most believable value is option 3) 20°C, 50°F, 293.15K.
