I believe this would be an exothermic reaction, As time increases, the temperature goes up meaning the heat from the system is going into the surroundings. Which indicates an exothermic reaction.
Answer:
Rutherford's atomic model explained how the electrons surrounded the nucleus of protons and neutrons. His model showed how J. J. Thomson's Plum Pudding model was incorrect.
Answer:
Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.

The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows
Heat = mc delta T
m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)
heat is therefore= 50 x 0.92 x 15 = 690
Nb: my answer has no units since the given specific heat capacity has no units
