Did you know?
WebBUT the electrical energy to create the laser was 100x as much as the energy actually absorbed by the fuel pellet. AND the energy of the explosion wasn't captured or harnessed in any way. So even if they did find a way to catch and channel that explosion to generate electricity it's still a tiny tiny fraction of the electricity used to power the laser. WebGiven heat q = 134 J. Given mass m = 15.0 g. Change in temperature: Δ T = 62.7 – 24.0 = 38.7. To find specific heat put the values in above specific heat equation: q m × Δ T = 134 15 × 38.7 = 0.231. However, a specific heat calculator can assist you in finding the values without any hustle of manual calculations.
