Qandaydir metallning massasi 1 kg. Uning dastlabki temperaturasi 40°C ga teng va uni temperaturasini 50°C gacha orttirish uchun 4600 J issiqlik kerak bo'ldi. Shu metallning solishtirma issiqlik sig'imini (J/(kg·°C)) aniqlang.

📝 Detailed explanation
Q = c·m·Δt formuladan:
c = Q/(m·Δt) = 4600/(1·(50-40)) = 4600/10 = 460 J/(kg·°C).
Javob: A) 460.
