The Kelvin scale is an absolute temperature scale threat can be used to calculate percent change in temperatures.The formula to convert Celsius to Kelvin is K=C+ 273.15.What is the percent change if the temperature rises from 21*C to 29*C?Round to the nearest tenth.
Since the degrees have equal size,
(29-21)/(21+273.15) * 100 = 2.7%
To calculate the percent change in temperature, we will use the formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100
Given:
Old Value (initial temperature) = 21°C
New Value (final temperature) = 29°C
To calculate the percent change, we need to convert both temperatures to Kelvin using the formula: K = C + 273.15
Old Value in Kelvin:
K1 = 21 + 273.15
K1 = 294.15 K
New Value in Kelvin:
K2 = 29 + 273.15
K2 = 302.15 K
Now we can calculate the percent change:
Percent Change = ((K2 - K1) / K1) * 100
Percent Change = ((302.15 - 294.15) / 294.15) * 100
Percent Change = (8 / 294.15) * 100
Percent Change ≈ 0.0272 * 100
Percent Change ≈ 2.72%
Therefore, the percent change in temperature from 21°C to 29°C is approximately 2.72% (rounded to the nearest tenth).
To calculate the percent change in temperature, we need to first convert the temperatures from Celsius to Kelvin using the given formula: K = C + 273.15.
For the initial temperature of 21°C:
K1 = 21 + 273.15 = 294.15 K
For the final temperature of 29°C:
K2 = 29 + 273.15 = 302.15 K
Next, we can calculate the percent change using the formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100
Percent Change = ((302.15 - 294.15) / 294.15) * 100
Percent Change = (8 / 294.15) * 100
Percent Change ≈ 2.72
Therefore, the percent change in temperature from 21°C to 29°C is approximately 2.7%.
