Answer:

5° C temp change

Step-by-step explanation:

Q = m c T

Given: Q =209 m = 10 c = 4.18 looking for T (change in temp)

209 = 10 * 4.18 T

T = 209 / (10*4.18) = 5° C

Answer:

5.0 °C

Step-by-step explanation:

To find the temperature change, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = heat energy (J)

-----> m = mass (g)

-----> c = specific heat capacity (J/g°C)

-----> ΔT = temperature change (°C)

You can find the temperature change by plugging the given values into the equation and simplifying.

Q = 209 J c = 4.18 J/g°C

m = 10.0 g ΔT = ? °C

Q = mcΔT <----- Equation

209 J = (10.0 g)(4.18 J/g°C)ΔT <----- Insert values

209 J = (41.8)ΔT <----- Multiply 10.0 and 4.18

5.0 = ΔT <----- Divide both sides by 41.8
