The correct Answer is:
To convert the temperatures from Celsius to Kelvin, we will use the formula: \[ \text{Temperature in Kelvin (K)} = \text{Temperature in Celsius (°C)} + 273 \] Now, let's convert each temperature step by step: ### Step 1: Convert 25°C to Kelvin 1. Start with the temperature: 25°C 2. Apply the formula: \[ 25°C + 273 = 298 K \] ### Step 2: Convert 38°C to Kelvin 1. Start with the temperature: 38°C 2. Apply the formula: \[ 38°C + 273 = 311 K \] ### Step 3: Convert 66°C to Kelvin 1. Start with the temperature: 66°C 2. Apply the formula: \[ 66°C + 273 = 339 K \] ### Summary of Conversions - 25°C = 298 K - 38°C = 311 K - 66°C = 339 K ### Step 4: Arrange the temperatures in order Now, we can arrange the converted temperatures in ascending order: 1. 298 K (from 25°C) 2. 311 K (from 38°C) 3. 339 K (from 66°C) ### Final Answer The correct sequence of temperatures in Kelvin is: **298 K, 311 K, 339 K** ---

To convert the temperatures from Celsius to Kelvin, we will use the formula: \[ \text{Temperature in Kelvin (K)} = \text{Temperature in Celsius (°C)} + 273 \] Now, let's convert each temperature step by step: ### Step 1: Convert 25°C to Kelvin 1. Start with the temperature: 25°C ...
