Answer:
There is 4184 Joule of energy required
Explanation:
Step 1: Data given
Mass of water = 50.0 grams
Initial temperature of water = 35.0 °C
Final temperature = 55.0 °C
Specific heat of water = 4.184 J/g°C
Step 2: Calculate the heat
Q = m*c*ΔT
⇒ Q = the heat transfer (in Joules)
⇒ m = the mass of water = 50.0 grams
⇒ c = the specific heat of water = 4.184 J/g°C
⇒ ΔT = The change of temperature of the water = T2 - T1 = 55.0°C - 35.0 °C = 20.0 °C
Q = 50.0g * 4.184 J/g°C * 20.0 °C
Q = 4184 J
There is 4184 Joule of energy required
