When 45 g of an alloy, at 25°c, are dropped into 100.0g of water, the alloy absorbs 956j of heat. if the temperature of the alloy is 37°c, what is its specific heat? a. 0.423 cal/g°c b. 1.77 cal/g°c c. 9.88 cal/g°c d. 48.8 cal/g°c try and explain with step by step or show work,

You can use this formula to help:

Where:

C = specific heat

q = heat

m = mass

t = temperature

What we know:

C = unknown

q = 956 J

m = 45 g

change in t = 12°C because 37°C - 25°C = 12°C

Plug known values into the formula:

C = 956 J / (45 g) (12°C) and we are left with a specific heat of 1.77J/g°C

Now, convert Joules to calories and then you get:

A. 0.423 cal/g°C

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
