Apiece of unknown metal weighs 217 g . when the metal absorbs 1.43 kj of heat, its temperature increases from 24.5°c to 39.1°c. determine the specific heat of the metal.

The specific heat of the metal is 0.451 J/g°C (This could be iron).

Explanation:

Step 1: Data given

Mass of the unknown metal = 217 grams

The metal absorbs 1.43 kJ of heat

The temperature increases from 24.5°C to 39.1 °C

Step 2: Calculate the specific heat of the metal

q = m*c*ΔT

⇒ q = the heat transfer = 1.43 kJ

⇒ m = the mass of the unknown metal = 217 grams

⇒ c = the specific heat of the metal =  TO BE DETERMINED

⇒ ΔT = the change of temperature = T2 - T1 = 39.1 - 24.5 = 14.6 °C

q = 1430 J = 217g * C * 14.6 °C

C = 0.451 J/ g°C

The specific heat of the metal is 0.451 J/g°C (This could be iron).

is has three carbons, so the answer is propylamine.

explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
