Which tool would you measure how different colors absorb the energy in sunlight is it beaker or thermometer

A Beaker is better.

Explanation:

Sunlight radiation generates electromagnetic waves with different wave longs , when all the waves move together our eyes see white light but objects like a beaker made with glass can refract and separate the waves and show it in different colors.

A thermometer only measure temperature using a substance like Mercury, it changes its volumen with the increase or decrease of temperature and that change is shown in the instrument.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
