Answer:
47947.52 J.
Explanation:
From the question,
Amount of heat given of (Q) = mc(t₁–t₂).................... Equation 1
Where m = mass of water, c = specific heat capacity of water, t₁ = initial temperature, t₂ = final temperature.
Given, m = 640 g = 640 g, c = 4.816 J/g°C, t₁ = 76 °C, t₂ = 28 °c.
Substitute these values into equation 1 above
Q = 640×4.816(48)
Q = 147947.52 J.
Hence the amount of heat given off is 47947.52 J.
Answer:
whats the question?
Explanation:
maybe sphere if its a shape though
Hello, some examples are Earth science, chemistry and Navigation science (don't know if there is called in this way).
In Earth Science we can talk about Geomagnetism.
In Chemistry, electrostatics and electrochemistry.
In Navigation science the compass.
Hope it helped.
