A15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°c to 175°c. calculate the specific heat capacity of iron.

0.46 J/gC

Explanation:

The specific heat capacity of a material is given by:

where

Q is the amount of heat absorbed

m is the mass

is the variation of temperature

For the piece of iron in the problem:

Substituting into the equation,

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea
