When 17.0 grams of an unknown metal is cooled from 35.0°c to 10.0°c it releases 862 joules of energy. what is the specific heat capacity of the unknown metal?

The specific  heat  capacity  of  unknown  metal  is  calculated  using the  following  formula

Q=MC  delta  T  where
Q= heat(862 j)
M=  mass  (17 g)
C=  specific  heat capacity=?
delta T = change in  temperature  (  35-10= 25 c)

by making  C the  subject  of the  formula  C=Q/m  delta T

=  862 j/( 17 g  x25 c) = 2.028 j/g/c

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
