Vacuum Flask Igcse Physics at Helen Mcewen blog

Vacuum Flask Igcse Physics. Heat struggles to leave or enter. A vacuum flask can keep hot liquids hot and cold liquids cold. The vacuum flask keeps the temperature of the liquid in the flask constant for a long time. It is the way in which heat reaches us from the sun through the vacuum of space. Vacuum flasks (or thermos) keep your drink hot or cold. Thermal radiation is the only way in which heat can travel through a vacuum. To keep water hot the flask must stop heat loss by conduction, convection and. (a) the vacuum flask is being used to keep a liquid cool on a hot day. The vacuum flask holds the liquid in an inner bottle. Outer wall of the flask is made a vacuum so that there is no air to form convection currents. The surfaces of the two glass walls. Describe how each feature helps to keep the liquid hot for longer. If the contents are hot, radiation is almost eliminated. A vacuum flask has many features to reduce not only thermal radiation but also conduction and convection. Explain how the labelled features of the vacuum flask keep the liquid.
