Science research, checking the significance of difference - which test

Hello dear Forum Readers,

I am looking for some help with doing the statistics for my master thesis. Unfortunately I had only basic introduction to statistics and need help at this point. My research is about checking if there is a difference in heating a specific material with ultrasound wave when starting with different initial temperature. I have results of 180 sec of heating for 5 different initial temperatures. 5temp_A_mean.png 9 heating curves (sampling 1s) for every initial temperature. I am supposed to check if the difference between them is statistically significant. Which test would you suggest? Is ANOVA a good solution here? I will be very grateful for any help.
