5. What would be the altitude of the bottom of a cloud mass if the surface temperature is 15^circ C and the surface dew point temperature is -10^circ C

## Step 1: Identify the given values from the problem. The surface temperature is and the dew point temperature is .## Step 2: Use the formula for calculating the altitude of the cloud base. The formula is:### \(Cloud base altitude = 125 \times (Temperature - Dew point temperature)\)## Step 3: Substitute the given values into the formula:### \(Cloud base altitude = 125 \times (15 - (-10))\)## Step 4: Perform the calculation inside the parentheses first, according to the order of operations (BIDMAS/BODMAS). This gives:### ## Step 5: Multiply 125 by 25 to get the cloud base altitude in meters. ## Step 6: Since the answer needs to be in kilometers, divide the result by 1000.
