Sure. And it'll stay cold for a while after taking it out of the fridge.
Yes.
Any kind of meat will change color while it is cooking. No matter what type of cooking method you are using.
While still bagged or wrapped, slide the roast into the crock pot to ensure that it is going to fit with enough room for air movement. If it fill fit without touching the side edges you will have a perfect roast. The average cook time for a 2.5 pound roast in a crock pot is six hours; more if you are adding vegetable to it, slightly less if it will not be disturbed while cooking. Removing and replacing the lid over and over to check the meat results in a loss of heat that increases the cook time.
While it is best to defrost meat before putting it in a crock pot, it is possible to produce good results without prior defrosting. Set the frozen meat on top of a layer of prepared root vegetables. Set the slow cooker on high for one hour, to bring the heat up to cooking level quickly. Then reduce to low and allow to cook according to directions for the size of the roast. A 3 lb. pork roast may require 8 to 10 hours if started frozen.

Why do bottom of utensils blackened while cooking?
Yes. To quote my my owners guide. The slow cooker will not recover heat losses quickly when cooking on low setting. Significant amounts of heat escape whenever the lid is removed; there for cooking time must be extended. Avoid frequent removal of the cover for checking cooking progress or stirring. Never remove cover during the first 2 hours when baking breads of cakes. it is not necessary to stir while cooking on LOW heat. While using HIGH heat for short periods, occasional stirring improves the distribution of flavors.
