Question

The initial temperature of a liquid is 50∘C. After which changes in temperature will the liquid be the same as the initial temperature? a decrease of 10∘C followed by an increase of 50∘C a decrease of 10 ∘ ∘ C followed by an increase of 50 ∘ ∘ C a decrease of 30∘C followed by a decrease of 10∘C a decrease of 30 ∘ ∘ C followed by a decrease of 10 ∘ ∘ C an increase of 140∘C followed by a decrease of 140∘C an increase of 140 ∘ ∘ C followed by a decrease of 140 ∘ ∘ C an increase of 245∘C followed by an increase of 245∘C

Answer 1

Answer:

  an increase of 140°C followed by a decrease of 140°C

Step-by-step explanation:

In order for the final temperature to be the same, the total amount of increase must match the total amount of decrease.

The changes shown above will result in the final temperature being the same as the initial temperature.
