Calculating Water's Final Temp after a 345 kJ Heat Boost
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover how to determine the final temperature of a water sample after heat absorption. Utilizing the concept of specific heat capacity and the formula q = mc?T, we calculate the change in temperature and reveal its new state. Experience the transformation from an initial tepid state to a drastically altered thermal condition.
