If water had a lower specific heat capacity, would ponds and lakes be more likely or less likely to freeze in winter?
Answer from: kountryboye25
A lower heat capacity means that less energy must be transferred to result in a temperature change. If less energy needs to be removed then it is easier for the surroundings to absorb it and make the lakes freeze.
Answer from: Quest
The answer is a) taiga because taigas are cold
Answer from: Quest
we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is
after 28s,
m/s
which i would round to 150 m/s as my final answer

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
