WebOn your paper, draw the cooling curve for SO2 starting at -50 °C and ending at -100 °C. At each region of the curve (plateau or diagonal), label the states of matter present. The following physical data may be helpful. Boiling point of SO2: -10 °C Melting point of SO2: … WebA heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions. Water has a high boiling point because of the strong hydrogen bonds between the water molecules; it is both a strong ...
WebUsing the phase diagram for water, we can determine that the state of water at each temperature and pressure given are as follows: (a) solid; (b) liquid; (c) liquid; (d) gas; (e) solid; (f) gas. Check Your Learning What phase changes can water undergo as the temperature changes if the pressure is held at 0.3 kPa? If the pressure is held at 50 kPa? WebThe cooling curve for pure liquid tin looks like this: It's just like the pure lead cooling curve except that tin's freezing point is lower. If you add small amounts of lead to the tin, so that you have perhaps 80% tin and 20% lead, you will get a curve like this: Notice the lowered freezing point of the tin.
WebFeb 24, 2024 · It is the second plateau in the curve. During this phase, the addition of heat will not lead to an increase in temperature, but to a change of state from liquid to gas. The temperature at which ... WebStep 1: Distinguish between the different states of matter at a given temperature and pressure using a phase diagram. Step 2: Use the provided vocabulary terms to identify the transitions taking...
