A sample of Aluminum absorbs 9.69 Joules of heat, upon which the temperature of the sample increases from 23.2°C to 30 .5°C. since the specific heat capacity of aluminum is 0.90 joules/(g•°C) the mass of sample is : A. 8.1 g
B. 65 g
C. 1.5 g
D. 72g

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.
