You can get a 3rd from something thats 115 degrees. It'll take hours of contact but it's possible.

The degree of a burn is how deep into the tissue it goes.

3rd is full thickness, all 3 layers, Epidermis, Dermis, Subcu fat.

140 at 1 second won't give you a 3rd but at 5 seconds of contact it will.

When I was 16, I worked at a Popeye's Fried Chicken. When I washed dishes, I used the hottest water that I could stand. I'd fill a sink with water full hot. It was usually about 135º. On the occasion that I got it up to 140º, that would be a little too hot, but I never had more than red skin that would be fine in an hour or two. And I spent a lot of time up to my elbows in that water.

I'm sure that would be far worse for a 4yo, but I wouldn't expect more that 2nd degree burns, max.
