I feel like brittle fracture could be a possibility, but it doesn't specifically mention temperature changes.

I'm a little confused by this question. I know there are different types of thermal failures, but I'm not sure which one is the best fit here. I'll have to review my notes.

Okay, let me see... When a colder liquid contacts a warmer metal surface, that's got to be thermal shock, right? I think I've got this.

Thermal shock, that's the one where the rapid temperature change causes the material to crack or fracture, right? I'll go with that.
