Sentences with phrase «water at ambient temperature»

When particles are dispersed in water at ambient temperature, energy is directed primarily to vaporization of water into steam, with a much smaller fraction resulting in heating of the fluid.

Not exact matches

The solution yields extracellular, water - soluble quantum dots from low - cost precursors at ambient temperatures and pressure.

Originally looking for a method to convert chemicals called organosilanes into silanols, the team combined organosilanes and water in the presence of the rhenium complex at ambient temperature and pressure.

Using diamond anvil cells (DAC), the team applied 2.5 GPa of pressure (25 thousand atmospheres) to pre-compress water into the room - temperature ice VII, a cubic crystalline form that is different from «ice - cube» hexagonal ice, in addition to being 60 percent denser than water at ambient pressure and temperature.

Choi and Cha, however, developed an efficient electrochemical method to oxidize HMF to FDCA at room temperature and ambient pressure using water as the oxygen source.

The team used temperature - controlled photoelectron spectroscopy in EMSL, the DOE's Environmental Molecular Sciences Laboratory on the PNNL campus, to determine how tightly one cyanide ion and one to three water molecules interact at the very low temperature of -438 °F (12 Kelvin) and again at ambient temperature of 80 °F (equivalent to 300 Kelvin).

We get about 4 cups from the food we eat and the water our body produces on its own, so the guidelines roughly translate into a daily recommendation of drinking 4 to 7 cups of water for women and 6 to 11 cups for men (assuming only moderate physical activity at moderate ambient temperatures).

I will howl at you that you can't tell me the glass of water has reached an equilibrium with the ambient environment because the ambient temperature is inhomogeneous and always changing.

If you still think that it is solar radiation which sets the temperature of the water in that glass bowl, then repeat the experiment on another similar clear sunny day in the same week of the year and at the same time, but when (due to weather conditions) the ambient temperature is significantly different.

People can complain their system does not deliver much hot water but systems have to be properly sized so as to allow for people washing dishes and taking showers and replacing the water with underground piped water which is at the temperature of the daily average ambient temperature.

All we would have would be water at the ambient local temperature.

If the bucket were dragged at sampling depth for a few minutes before extraction, the walls of the bucket would have come near the ambient water temperature, slowing heat loss from the captured water.

Dissolved GHG flux (Fd) was calculated as: where Csur is the gas concentration in surface water, Ceq is the gas concentration when in equilibrium with the atmosphere at ambient temperature (global atmospheric concentrations were used), and k is the gas exchange velocity calculated as: where Sc is the Schmidt number calculated from empirical third - order polynomial fit to water temperature and corrected at 20 °C.
