Hi !
When the food is cooled outside the refrigerator using the ice bath, then the temperature of the food reaches 140⁰F (60⁰C) within the two hours and 70⁰F with in a total of 6 hours.
1. I personally (Average teen) use social media about 3-4 hours a day. I spend most of my time online watching You tube videos, this app and snap chatting my friends.
2. I don't think me being on social media has a influence on me because I know my limits and I know that life is not revolved around social media and you can do other activities besides being on your phone all day. (Sports, music, arts, etc.)
3. I think the positive side of me using social media is I can connect with my friends and family, and keep up with that is going on in the world. However, many many people are affected by bullying online, which is a negative thing that should never happen.
4. I think I spend a reasonable amount of time on social media, considering most of it is for school or educational purposes.
Sorry for the long reply, but hope you can get some inspiration from this :)
