You have 1.00g of two metals a&b. The specific heat of metal A is 0.568j/g• °c and metal B is 1.34j/g•°c both are heated to a temp. Of 80°c. Which will heat up fastest

Metal A will heat up faster

Explanation:

Step 1: Data given

Mass of the 2 metals = 1.00 grams

The specific heat of metal A is 0.568j/g * °c

The specific heat of metal B is 1.34j/g*°c

Initial temperature = 80 °C

Step 2: Calculate energy needed

A high specific heat value means that it takes MORE energy to raise (or lower) its temperature.

A low value means that it does not take very much energy to heat or cool it.

Step 3: Calculate energy needed to raise 1 °C

Q = m*c*ΔT

Metal A: Q = 1.00g * 0.568 J/g°C * 1°C

Q = 0.568 J

Metal B Q = 1.00g * 1.34 J/g°C * 1°C

Q = 1.34 J

We need 0.568 Joules energy to raise the temperature with 1°C for metal A.

We need 1.34 Joules energy to raise the temperature with 1°C for metal B.

Since we need less energy to raise the temperature for metal A, it will heat up faster.
