I'm driving from Sydney to Melbourne (approximately 12 hours trip) and I'm wondering if it's safe to have this Galileo's Thermometer in my car during the trip if it's going to be a scorcher of a day. It could easily reach 35 degrees Celsius or over during the trip. I'm a little worried that it might explode. Any help much appreciated!
I don't know what atmosphere you have inside the thermometer, but either way I think it's hardly the case that you reach the autoignition temperature of paraffin (gasoline undergoes autoignition at 246-280 °C).
