Obtain two 50 ml beakers and in one add 30 ml of water and in the other add 30 ml of ethanol. drop a piece of an ice cube into each beaker. record your observation. can you explain the scientific theory behind your observations? quickly weigh a piece of ice in an empty beaker and then allow it to melt. record the volume and weigh it again. record your values. what are the differences and similarities in your weights before and after the ice melted? 24.12 metted - 2002 can you list four other intensive properties? d. evaluate the graph of mass versus density. what is the appropriate function or equation for this graph? using the your knowledge on gas law and density, calculate the molecular mass of a liter of a gas collected at 25°c, and 1 atm. evaluate the observation that ice-cube floats on top of water but sinks in ethanol. what gas state functions (variables) affect density? bb- evaluate how kinetic energy is affected by density. discuss the relationship between partial pressure and density.
