Why does temperature increase with mass? If density increases ,volume decreases and if density decreases , volume increases. So density*volume=mass remains same as before. Gravitational pressure increases the more mass there is, and that pressure creates energy that increases temperature. Why does it take longer to heat up a larger volume of water? Simple: you’re […]
Which two factors are needed to calculate the velocity of an object?
Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
