Arranging the words in alphabetical order:

To determine which word comes first in alphabetical order, we need to compare the first letters of each word. If the first letters are the same, we then move on to the second letters and so on until we find a point of difference.

Let's arrange the given words in alphabetical order:

1. Temperature
2. Tenacious
3. Temple
4. Tenant
5. Terminate

Explanation:

- The first word in the list is "Temperature." The first letter is 'T.'

- The second word is "Tenacious." The first letter is also 'T.' Since the first letters are the same, we move on to the second letters.

- The second letter of "Temperature" is 'e,' and the second letter of "Tenacious" is 'e.' Again, we move on to the third letters.

- The third letter of "Temperature" is 'm,' and the third letter of "Tenacious" is 'n.' Here, we have found a point of difference. Since 'm' comes before 'n' in alphabetical order, "Temperature" comes before "Tenacious."

- Moving on to the third word, "Temple." The first letter is 'T,' which is the same as the previous two words. We then compare the second letter.

- The second letter of "Temple" is 'e,' and the second letter of "Tenacious" is 'e.' Again, we move on to the third letters.

- The third letter of "Temple" is 'm,' while the third letter of "Tenacious" is 'n.' Similar to the previous comparison, 'm' comes before 'n' in alphabetical order. Therefore, "Temple" comes before "Tenacious."

- The fourth word is "Tenant." The first letter is 'T,' which is the same as the previous three words. We then compare the second letter.

- The second letter of "Tenant" is 'e,' and the second letter of "Tenacious" is 'e.' Once again, we move on to the third letters.

- The third letter of "Tenant" is 'n,' and the third letter of "Tenacious" is 'n.' Since both letters are the same, we move on to the fourth letters.

- The fourth letter of "Tenant" is 'a,' while the fourth letter of "Tenacious" is 'c.' Here, we have found a point of difference. 'a' comes before 'c' in alphabetical order. Therefore, "Tenant" comes before "Tenacious."

- Finally, we have the word "Terminate." The first letter is 'T,' which is the same as the previous four words. We then compare the second letter.

- The second letter of "Terminate" is 'e,' while the second letter of "Tenacious" is 'e.' Again, we move on to the third letters.

- The third letter of "Terminate" is 'r,' and the third letter of "Tenacious" is 'n.' Here, we have found a point of difference. 'r' comes before 'n' in alphabetical order. Thus, "Terminate" comes before "Tenacious."

Therefore, the word that comes first in alphabetical order is "Temperature."
