A scientist measures the vapor pressure of a liquid. At 15° C, the vapor pressure was 19 kilopascals. At 25° C, it was 31 kilopascals. At 35° C, it was 59 kilopascals. Which statement can be inferred from the observations?

A. Increasing temperature alters the volume of the liquid
B. Increasing temperature decreases vapor pressure
C. Increasing temperature does not affect vapor pressure
D. Increasing temperature increases vapor pressure

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
