This is due to friction. Friction acts between the car tires and the surface. On a normal road the friction would be greater than on ice.
Any car needs traction to accelerate, turn or stop. Your tires can't grip on slippery roads, it needs clean and dry asphalt for maximum traction.
WHY!It is because the ice makes the friction between the tires and the pavementgreater.
Longer as compared to what?
Depends upon conditions. Studies show that Most cars with ABS stop faster on wet and even dry pavement. However ABS cars take longer to stop on ice, snow, and gravel. Personally I really like them in rain, and CANNOT STAND THEM on snow/gravel.
Assuming all else is equal (no specialized snow/ice tires, equal driver reaction time etc.) it will take a lot longer. Up to ten times longer. If the ice is on a downward-sloping hill, there is a chance that a car cannot stop at all, until it slides to the bottom of the hill or hits an object along the way down. Winter tires, either studded or not, SIGNIFICANTLY help on ice, especially studded. Although Illegal in some areas/states, studded tires make driving on snow/ice as effortless and safe as on dry asphalt. If you're ever driving on slippery roads and come upon a situation where you need to brake hard, remember that if you slam on the brakes you will slowly start stopping, but you will not be able to change direction--you will keep going straight until you stop. I found that many times it's safer to not stop, and simply turn your car to the left or right (which is much easier/faster to do than coming to a complete stop), and simply go around the obstacle that would otherwise force you to stop. If you're at a busy intersection, this might not be good advice, but I'd still rather slide my car into a ditch alongside the road than rear-end someone and have my insurance rates raised.
Because there is more ice.
Car behind, you should travel at a speed you at stop at.The driver should take into account driving conditions. I hear you say but the car in front should have moved off as no traffic was coming. What if the car had stalled or the driver was having a heart attack?
6-8 seconds
Yes. Larger quantity of ice while take longer to melt.
Bout 7 minutes when it's in ice, longer in the fridge.
It depends on your ice cream maker. If you use a gel canister model, 20 minutes. Longer and your ice cream starts to melt. An ice and salt ice cream freezer can take a bit longer. Compressor ice cream makers take between 35-40 minutes. For more on the different kinds of ice cream makers and how they work, see The Ice Cream Maker (link below).
An ice bath is where you take whatever you just blanched and put it in ice water. The purpose is to stop the blanched item from cooking/softening.
a little bit longer because even though the freezer is cold the back is colder than the front and therefore the ice may take a while longer
