21.7 mL of gas at 98.8 kPa is allowed to expand at constant temperature into a 52.7 mL container. What is the new pressure of the gas?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

How many joules of heat are required to raise thetemperature of 750 g of water from 11.0 °c to 19.0 °c?

During an experiment, ice and water were placed in a perfectly insulated thermos flask at 0 °c. describe this system when it phase reaches equilibrium.
