2003 Metu Chemijos Valstybinio Egzamino Atsakymai About Pferden Stando File

It seems you are looking for content related to the and a mention of "pferden stando" — which appears to be a mix of German ( Pferden = horses) and Lithuanian ( stando might be a misspelling of standų or stendo ?).

A horse (800 kg) pulls a cart with a force of 600 N over 50 m. Calculate the work done. Then, if this energy is used to heat 100 g of water, what is the temperature rise? (Specific heat of water = 4.18 J/g°C) It seems you are looking for content related

Work = Force × distance = 600 × 50 = 30,000 J. ΔT = Q / (m·c) = 30,000 / (100 × 4.18) ≈ 71.8°C. 4.
