Question

1. convert one-hundred degrees celsius to kelvin.

1. convert sixty-four degrees fahrenheit to celsius.

1. convert (-13.0) (\text{°c}) to kelvin.

1. what is the preferred temperature scale used in scientific laboratories? use complete sentences to receive full credit.

Explanation:

Step1: Use Celsius to Kelvin formula

$T(K) = T(^\circ C) + 273.15$
$T(K) = 100 + 273.15$

Step2: Calculate the value

$T(K) = 373.15$

Step1: Use Fahrenheit to Celsius formula

$T(^\circ C) = \frac{5}{9} \times (T(^\circ F) - 32)$
$T(^\circ C) = \frac{5}{9} \times (64 - 32)$

Step2: Simplify the expression

$T(^\circ C) = \frac{5}{9} \times 32$

Step3: Calculate the value

$T(^\circ C) \approx 17.78$

Step1: Use Celsius to Kelvin formula

$T(K) = T(^\circ C) + 273.15$
$T(K) = -13.0 + 273.15$

Step2: Calculate the value

$T(K) = 260.15$

The Kelvin scale is preferred in scientific laboratories because it is an absolute temperature scale with no negative values, which aligns with the theoretical behavior of matter (absolute zero is the lowest possible temperature, where molecular motion stops). It is also the standard SI unit for temperature, ensuring consistency across scientific research.

Answer:

1. $373.15$ K
2. $\approx 17.78$ $^\circ C$
3. $260.15$ K
4. The preferred temperature scale used in scientific laboratories is the Kelvin scale.
