The last days it has been snowing here (Holland)My car is covered with about 20 cm of fresh snowI don't need the car in about a few daysComing nights become cold with temps up to -15 degrees C.If snow is present on an ice floor it will grow thicker lots slowerSo, hence the question: My car is under 20cm of snow, coming nights are getting very cold (temps up to -15 C), is it better to leave the snow on my car?
If your lettuce is still green and looks crisp, it is probably still good and safe to itI have managed to keep some heads of lettuce for over 3 weeks and they were perfectly good.
If its just you eating it then sure it should be fineBut if cooking for multiple people id say dont take the risk of food borne illness that will make everyone sickJust run down to the store and grab a fresh bag.
vegetables don't secretly spoil in such a way that you cannot tellIf it looks good it is goodsimple as that.
Something to remember is that the snow is covering two entirely different objects (Materials) As ice is directly temperature sensitive then it is control directly by contact or any controlable product (ie snow, temperature etc.) Your car however, is metal and therfore is a conductor of cold or warmMetal is directly affected but also indirectly affected but temperature changes both inside and outside, thus the snow only controls in part what happens to your carAir circulation (or lack thereof) inside your car will affect as will the trapped air underneath your car to act as an insulationBut it will also trap a measure of moisture that will inhibit rusting through timeYour scenario of comparing ice and your car covered with snow doing having the same effects are like saying that an apple and an orange will do the same thingsComparable to a point but not identical in all ways, both will taste good when ripe but different, and both will spoil if over ripeSuggestion, remove the snow from your car when your car is needed, or when you have time and allow the air to circulate around it to dry it off and slow down the rust procedureRusting is a long drawn out process that any moisture/air mixture will affect metal adversely.
