Asubstance has a specific heat of 0.870 j/g°c. it requires 2,000.0 joules to increase the temperature of 10.0 grams of the substance from its original temperature to its final temperature. by how many degrees did the substance increase? a 87.0°c b 174°c c 230°c d 1,740°c

230 degrees centigrade

Explanation:

H= mass× specific heat capacity× increase in temp. ==> Increase in temp = H/mc

Temp rise = 2000/ 10× 0.870 = 229.89°

 Note= specific heat and mass are in gram, so ther's no need for conversion

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
